Configuring resource monitoring for third-party resources

Resources associated with probes that monitor non-Hitachi resources are referred to as third-party resources. You monitor these resources by setting up separate alerts and indicators using the Analyzer detail view server UI.

Using detail view email and syslog alerts

You must configure a separate set of alerts to monitor third-party resources.

NoteIf you have not installed any probes that are not supported by Ops Center Analyzer, it is not necessary to set up alerts within Analyzer detail view.

Adding detail view alerts

You can set alerts in detail view and configure notifications for them.

  1. Access Analyzer detail view from the More Actions menu.

  2. In the application bar area, click the Alerts list and select Add Alert.

  3. In the Alerts Details section, enter the following details:

    • Name A unique name with maximum length of 100 characters. (Alert name cannot contain special characters except underscore and space.)
    • Severity Severity level - Critical is red and Warning is amber.
  4. In the Alert Resource section, enter the following details:

    • Select Select the target to add the alert.
    • Choose Select one or more target instances.
    • Include future instances Automatically apply the alert to future target instances. (This option is only available if all target instances are selected.)
    • Create Alerts on Select the resource for which you want to set the alert.
    • For Instance(s) Select the resource instance.
      NoteThe resource instances can be filtered based on certain criteria. For example, the disk type is displayed for RAID Pool Tier resource. You can filter the resource instances using the filter option (disk type) and then set alerts for the filtered resources. You can also choose to skip resource instances from the filtered list.
    • Include future instances Automatically include any future resource instances. (This option is only available if all resource instances are selected.)
  5. In the Alert Condition section, you can set alert condition on performance and configuration metrics:

    GUID-51F30C9D-52A2-4091-9190-2A2D7D3FC639-low.png

    • To set up the alert condition for configuration metrics, enter the following details:
      • Metric Select the configuration metric.
        NoteIf a resource does not have a configuration metric for alerting, the configuration metric is not displayed in the list.
      • Condition Select the condition type. Metrics with numeric values use: greater than, between, and less than. Metrics with string values use the having condition.

        NoteUnder certain circumstances, the Analyzer detail view cannot identify whether a metric is a numeric or string value. When this occurs, all condition types are listed in the GUI (greater than, between, less than, and having). To select the proper condition, you must know whether the metric is a numeric value or a string. You can find the value by running the query in Report Builder. See, Identifying the metric value.
      • Threshold Type or select a threshold value. (Certain metrics with string values include predefined thresholds.) The value set for the having condition is saved and is available for other users.

        The threshold value specified in this field applies to all the selected resource instances.

        Note The threshold field supports alphanumeric characters, hyphen (-), underscore (_) , comma (,), colon (:), at (@), slash (/), dot (.), and space.
      • Customize Threshold For Resources Click this link to customize the value for a specific resource instance.

        The Customize Threshold for Resources window is displayed. The instances selected in the Alert Resource section are displayed.

Identifying the collection interval

When setting up an alert on the resource, you must know the data collection interval of its metrics, because the criteria are set based on the data collection interval.

You can set an alert for a metric based on the number of samples for a multiple of the collection interval. For example, if the data collection interval of a particular metric is 5 minutes, you can set alert with a criteria of 1 sample out of 5 minutes, 2 samples out of 10 minutes, 1 samples out of 10 minutes, and so on.

GUID-40A99FF9-5741-42B1-868A-7286735CD24F-low.png

You can find the data interval of the metric by running a query in Report Builder. For more details on the report builder, see Creating custom reports using the Analyzer detail view Report Builder. To identify the data collection interval of a particular metric, do the following:

Procedure

  1. In the left pane, go to Reports > Build.

Monitoring third-party resources using detail view dashboard indicators

Analyzer detail view has a separate dashboard that you use to monitor the status of third-party resources.

NoteIf you have not installed any probes that are not supported by Ops Center Analyzer, it is not necessary to configure the detail view dashboard.

Understanding detail view indicators

You can set the detail view Dashboard view to show traffic light indicators or a heat map.

To view the details of a violation, click the indicator icon.

The detail view dashboard dock is available on every node in the resource tree, and it contains the dashboard widgets from all of the subnodes. You can view the indicators added by the other users, and you can select these indicators to appear on the dashboard.

Indicator view

The Indicator view provides an overall score of each resource, along with the health assessment of its components using traffic light indicators. In the Indicator view, the health score is expressed as a percent value.

In addition to the high-level resource, each of its components is assigned a score and an indicator. The score is the total number of threshold violations. You can hover over the score to view details of the Critical and Warning threshold violations.

The indicator for each component is determined by the proportion of critical and warning threshold violations for each component. The Critical threshold violations have a greater (negative) effect on the Indicator than Warning threshold violations.

At a high level, the indicators represent the following:

  • GreenRepresents a score above 70%.

    Overall, the resource is healthy. The resource and its components rarely violate Critical or Warning thresholds.

  • AmberRepresents a score above 50% but below 70%.

    Indicates the resource is reasonably healthy but the user is cautioned to monitor this resource closely. The resource and its components occasionally violate Critical or Warning thresholds.

  • Red Represents a score below 50%.

    Indicates that the resource is not healthy and might require immediate attention. The resource and its components frequently violate Critical or Warning thresholds.

The following factors influence the indicator scores:

  • The frequency of thresholds violation. A large number of thresholds leads to a lower score. The number of Critical threshold violations affects the indicator score more than the number of Warning threshold violations.
  • The intensity of the threshold violations is the magnitude of the violation each time it occurs. A violation of a Critical or Warning threshold by a greater margin has a higher effect on the score.
Heat map view

The heat map view displays resource health using a miniature graph of any violations of critical and warning thresholds. The values in this view (except for the display) are equal to those in the Indicators view.

Adding detail viewdashboard indicators

You can create custom indicators and specify criteria like resource, metrics, and thresholds at the Group level node in the resource tree.

ExampleGUID-2F978E08-E9E5-49FA-92E0-E5FBE4BD97EA-low.jpg

Procedure

  2. In the detail view Dashboard view, click GUID-7DE11E95-F6C1-4B67-97E4-0232E5DA947D-low.png on the dashboard bar.

    The Manage Indicators window opens. The default indicators are disabled (and cannot be removed), but you can use the Show option to control which indicators are displayed.

    GUID-7DCC38C2-652F-463D-AED1-C3152E55BB92-low.png

    NoteIf you click on an Instance level node (rather than the Group), the window is named View Indicators and all the buttons are disabled except Close.
  3. To add additional indicators, click Add Indicator.

  4. In the Add Indicator window, enter the following details:

    • Name A unique name for the specific target. This appears as a column name on the dashboard.
    • Selected Node Shows the node to which indicators are added.
    • Select Resource Select a resource from the list to view all the subnodes.
    • Select Subpath Select one or more subpaths. In the example, LDEVs is one of the subnodes of VSP G/VSP F/VSP E node. However, the LDEV (source) is connected to the VSP G/VSP F/VSP E (target) through multiple paths in the subtree of the VSP G/VSP F/VSP E node. In the Select Subpaths box, list all such paths.
    • Select Metric(s) Choose the metrics, and then select from the list of Indicator Thresholds. If no thresholds are defined, you can create new ones by selecting Add new threshold.

Exporting, importing, and resetting detail view dashboard indicator thresholds

You can export indicator thresholds from one Analyzer detail view and import them to other Analyzer detail view for consistency. You cannot view or edit these thresholds values outside of Analyzer detail view. You can also reset the thresholds to factory settings.

  1. Select Tools Ops Center Analyzer detail view to start the detail view GUI.

  2. In the application bar, click the Manage menu.

  3. In the Administration section, click the Manage Thresholds link.

  4. In the Manage Thresholds window, click the Configured Thresholds link.

    The Configured Thresholds window opens and lists all the configured thresholds on the server. All columns except Warning and Critical have filters.
  5. Click the Export link.

    The export file is encrypted with the name of ExportedThresholds.enc by default. (Any filtered columns are exported as well.)
  6. To import a thresholds file, click the Import link.

  7. Click Select File to browse to the threshold export file, and click Upload.

    The Import threshold file information window displays details such as Analyzer detail view version, URL, and supported probe list, for which you are importing the thresholds.
  8. Click Import.

    The configured thresholds table is updated with the imported thresholds.
  9. Click the Reset Defaults link to reset the threshold indicators to the factory default settings.

  10. Click Yes, to confirm your choice.

    This restores the default thresholds and updates the display.

Editing and deleting detail view dashboard indicators

You remove detail view dashboard indicators and edit thresholds. The edit and delete options are available at the Group level node.

Note
  • You cannot edit the indicators added by other users. However, a user with administrator rights (permissions) can edit the indicators added by other administrators and normal users.
  • You cannot delete the default indicators.
  • You cannot delete indicators added by other users.
  • The Delete icon is disabled for indicators that are in use.
  • Users with administrator privileges can delete the indicators added by administrators and normal users.

Procedure

  1. Select Tools Ops Center Analyzer detail view to start the detail view GUI.

  2. In the Dashboard view, choose a resource from the tree.

    A tab for the resource opens with a list of indicators. (Default indicators are shaded and cannot be changed.)

    The Manage Indicators window opens.

    GUID-3992EE3F-FDED-4117-915B-59E260258816-low.png

  4. You can select a threshold for an indicator from the list, or delete an indicator by clicking the Delete icon.

  5. Click Save when your changes are complete.

Customizing detail view dashboard indicator thresholds

You can define custom thresholds for Analyzer detail view dashboard resource indicators from the Manage menu. The thresholds that you set in this window appear in the Indicator Thresholds menu of the Add Indicator window.

Dynamic thresholds

Dynamic thresholds are supported for certain devices. You can add the threshold on the storage port throughput based on the speed of the switch port that the storage port is connected to. Analyzer detail view currently supports the dynamic thresholds for the following probes, resource types, and metrics.

Probe Resource type Metric
Hitachi Enterprise Storage RAID Port Transfer Rate
Hitachi AMS AMS Port CTL 0 Transfer Rate, CTL 1 Transfer Rate
EMC VMAX VMAX Port MBps Ops
EMC VNX Block VNX Block Port Total Throughput
IBM XIV® IBM XIV® Local FC Port Total Throughput

Procedure

  1. Select Tools Ops Center Analyzer detail view to start the detail view GUI.

  2. In the application bar, click the Manage menu.

  3. In the Administration section, click the Manage Thresholds link.

    The Manage Thresholds window opens.
  4. In the Manage Thresholds window, supply the following information:

    • Select Probe Select the probe from the list.
    • Select Resource Type Select the resource from the list.
    • Select Metric Select the metrics for the selected probe and resource type.
    • Add Indicator Thresholds Click Add Thresholds and type the label for the threshold, and then set the warning and critical thresholds as follows:
      1. Type the threshold name and set the threshold value.
      2. Configure Advanced options to set threshold direction (Forward or Reverse):
        • For Forward Threshold, the critical threshold should be greater than warning threshold. In this case, the threshold is violated when the metric value exceeds the defined threshold. By default, the threshold direction is Forward.
        • For Reverse Threshold, the warning threshold should be greater than critical threshold. In this case, the threshold is violated when the metric value is less than the defined threshold. Reverse direction thresholds are useful when evaluating metrics like Read Hit for VMAX Volume or Cache Usage. If the Read Hit rate falls below the threshold, the cache is underutilized and performance suffers.
    For devices that support dynamic thresholds, the following additional options are displayed:
    • Specify Dynamic Threshold Value Select to specify a dynamic threshold value.
    • Select Resource Path Select the appropriate switch port path.
    • Select Attribute Select the attribute and provide the Warning and Critical threshold values (percentage).
  5. Click Save.

Viewing detail view alert violations

You can view the details of alert violations based on the resource for which the alert occurred.

  1. Select Tools Ops Center Analyzer detail view to start the detail view GUI.

  2. In the application bar area, click the Alerts menu, and select Violations.

    The Alert Violations tab opens.
  3. Click the plus icon (+) to view details and a graph of the violation.

  4. In the Acknowledge column, select the check box to acknowledge the alert if you created it.

    NoteThe alerts generated on the real-time data will start showing under the Alerts Violation tab, only after the data (for which the alert is generated) is collected through default flow.

Renaming instance-level nodes in the resource tree

You can change the instance-level node names in the resource tree. The new name is reflected across all the occurrences in the Analyzer detail view.

  1. In the resource tree, right-click the instance-level node that you want to rename, and then click Rename.

  2. Enter the new name, and then press Enter.

  3. Click Yes to confirm.

    NoteIf you want to restore the system-defined (default) name, you can revert it with the Undo Rename (GUID-C7B8BF93-2679-4A5D-B6D1-C72D0A9B162C-low.png) option which is displayed when you hover over the renamed node in the resource tree.

Using Analyzer detail view Health Check

Monitoring performance is essential for effective data center management. System administrators require access to resource information at any moment to help understand its performance.

The Analyzer detail view Health Check provides overall visibility of your resources across the monitoring environment (storage systems, switches, hosts, and hypervisors) in treemap view in the same pane, where at a glance the system administrators can identify the problematic area and drill-down to view the health of underlying resources.

The Health Check view indicates overall resource health using the color and size of a block. Where the color represents the health of the resources and the size of the block represents the most relevant attributes of the target, like Capacity for the storage systems, ports for the switches, and so on.

You can download and schedule the Health Check report.

NoteYou can navigate to the Health Check view by clicking the Health Check option in the left pane. When you first log on to the Analyzer detail view, Health Check is the default view.

GUID-48DCE9F1-7470-4C43-B2A1-0844EFC989CD-low.jpg

Understanding the Health Check view

Health Check shows overall resource health using the size of block, health score, and color representation.

  • The size of the block represents the most relevant attributes of the target:
    • Host: Total Capacity
    • Hypervisors: Total Capacity
    • Storage Systems: Total Capacity
    • Switches: Port count

    GUID-1727CA61-B4B9-4C80-B719-0ADEE8DFC593-low.jpg

    The grey block in the Health Check view represents that the data is not available or the available data is not sufficient to calculate the health.

  • The resource color and score represent its relative health. The health score is a number between 1 and 100 that provides an objective (numerical) view of the health of a resource. The higher number (max 100) indicates a healthier resource; whereas a resource with a lower health score (closer to 0) represents a less healthy resource. The health score is calculated based on the number of times a metric of the resource has exceeded the warning or critical threshold that is defined for that resource and metric combination. A large number of critical and warning thresholds violation leads to a lower score. Similarly, the health is represented in the color, closer to Red means a lower score and closer to Green indicates a higher score.
  • You can filter the Health Check view based on the health score with slider (available in health score bar). The slider moves in five unit increments. The filtered state is preserved when you click on any resource and move to next page. The filter can be changed on this page.

    GUID-7B46A0EB-06A0-4EB5-A343-1A139A9088E1-low.jpg

    NoteFilter on health score does not update the table entries.
  • Indicators in the Health Check are also calculated in the similar manner and result is depicted in the traffic light display red (Critical), amber (Warning), and green (Normal) indicators:

    • Green Indicates the resource is healthy.
    • Amber Indicates the resource is reasonably healthy but the user is cautioned to monitor this resource closely.
    • Red Indicates that the resource is not healthy and might require immediate attention.

Identifying the affected resources and metrics
