Availability KPIs are applicable at the instance level only. All the availability KPIs are clubbed together in one category named “availability.” Every instance screen displays it on top of the category list. Availability KPIs represent the state of instances, and ports. The state can be either up or down. The values are binary (0 or 1).

Metric – Availability

 

1This displays a group KPI.
 2This displays a KPI under a group KPI.
3Bar displaying KPI status. When Events option is selected, KPIs having events are displayed.

Red block: When a particular KPI is unavailable and meets the criteria for persistence or suppression, HEAL application creates an event and is displayed as a Red block on top of pink block.

Pink block: It indicates a particular KPI is unavailable for a specific time range.

Green block: It indicates a particular KPI is available for a specific time range.

Pink and Red colors represent separate blocks as described above. They don’t represent any shading of colors with respect to event counts as you may have observed in Heat Map screen.

Hovering on a green block displays the KPI availability time interval, as shown below.

Hovering on a pink or red block displays KPI unavailability time interval, unavailability count, and events count during this interval.

Heal Host Availability

This KPI collects and publishes a single KPI for each component instance data received by the KPI processor. This assists in determining whether a host is available or not and sends notifications or alerts when the Supervisor Agent becomes unavailable or down.

This feature is only available if the Supervisor Agent is installed, up and running on the target server, and is not currently available for remote monitoring.

Important: The Supervisor Agent must be updated to the latest version as specified below.

Latest Version: supervisor_solaris_10_2.1.1.12 or supervisor_Linux_10_2.1.0.12.

The HEAL Host Availability is displayed as follows.

HEAL Host Availability

1Green block: It indicates a host is available for a specific time range.
2Pink block: It indicates a host is unavailable for a specific time range.
3Red block: When a host is unavailable and meets the criteria for persistence or suppression, the HEAL application creates an event, and is displayed as a Red block on top of the pink block.

 

URL Availability

This KPI collects and publishes the availability status of specified URLs. It helps in determining whether a URL is reachable or not and sends notifications or alerts when a URL becomes unavailable.

  • Grey block: Indicates that the metric was not collected for a specific time range.
  • Green block: Indicates the URL is available for a specific time range.
  • Pink block: Indicates the URL is unavailable for a specific time range.
  • Red block: When a URL is unavailable and meets the criteria for persistence or suppression, the HEAL application creates an event, and it is displayed as a Red block.

Below is an example of how URL Availability KPIs are displayed.

Displays the status of the URL, whether it is available or not, with time intervals shown in green, pink, red, and grey blocks based on availability.

 

 

Sample Components with Availability KPIs

Below are examples of Sample Components with Availability KPIs.

IIB KPIs

When you map IIB component instances to IIB components using Control Center, you can view IIB KPIs in HEAL. Integration Node Status KPI provides the status of the IIB node, whether it is active or inactive. Integration Server Status KPI provides information on the availability of the server and whether the server is up and running.

IBM Storage KPIs

When you map SAN_NAS instances to IBM storage component using Control Center, you can view IBM Storage KPIs in HEAL. The IBM Storage Disk Group KPI provides information about the status of disk groups. The IBM Storage Drive Avail Group KPI provides information about the status of the storage Mdisk. The IBM Storage Host Avail group KPI provides information about the status of storage hosts.
