Pools Parameter

The parameters available in the Pools are:

Pools Parameter	Description
Failed Tasks	Shows the total count of the failed tasks executed in the Director Console on different pools and LogPoint instances in the last seven days.
Completed Tasks	Shows the total count of the completed tasks executed in the Director Console on different pools and LogPoint instances in the last seven days.
Pending Tasks	Shows the total count of the pending tasks executed in the Director Console on different pools and LogPoint instances in the last seven days.
Idle Percent	Shows the CPU percentage of a LogPoint that is unused in any process for a particular instance of time.
Available Memory	Shows the available memory that the system can use, which includes free memory and cached memory.
Free Memory	Shows the available memory after allocating the memory to all the available processes.
Inactive Memory	Shows the total memory allocated to the processes that are no longer running.
I/O Wait	Shows the time (in milliseconds) for which the CPU is idle while waiting for an I/O operation to complete.
Average Load	Shows the average value of the CPU load over the last five minutes. Only an entirely idle CPU has an average load of zero.
Normalizer Load	Shows the percentage of load on the CPU due to normalizer services. It lets you track the tasks performed by the normalizer and its impact on the CPU.
Server Roles	Shows the count of the server roles used in the pools or the LogPoint instances. The server roles in the LogPoint are LogPoint Collector and Distributed LogPoint.
Device Count	Shows the total number of device IPs available in the LogPoint at a particular instance of time.
Average Doable EPS per Normalizer	Shows the total number of events and processes that a normalizer can handle per second.
Stopped Services	Shows the list of services if they are not working.
Normalization EPS	Shows the total number of events processed by the normalization layer per second.
Store Handler EPS	Shows the total number of events processed by the storage layer per second.
Total Disk Usage	Shows the total percentage of the disk used in the system.
Open Files	Shows the total number of open files.
Disk Usage	Shows the free disk space for each partition of all Logpoint instances in the pool.

Monitoring the Overview of Pool

1. Go to Dashboard.

2. Click Overview in the required Pool widget.

The Network Graph represents the pools, their LogPoint instances, and its parameters.

Configuring Parameters

1. Go to Dashboard.

2. Click the Configure () icon in the required Pool widget.

   Configure Pool Icon

3. Enter the Duration and the Threshold values, and change the direction of each parameter as required.

   Configure Pool Settings

   In the screenshot above, the I/O Wait of the Pool becomes unhealthy:

   • if it is more than 50 ms on average over the last 6 hours or

   • if it becomes more than 50 ms at any point of time over the last 6 hours.

     Similarly, the Available Memory of the pool becomes unhealthy:

   • if it is less than 5% on average over the last 6 hours or

   • if it becomes less than 5% at any point of time over the last 6 hours.

4. Click Save.

Monitoring the Visualization of Parameters

Drill-down allows you to track the system and memory status of all the pools and their LogPoint instances.

The LogPoint instances update their data to the Fabric Proxy every five minutes by default. The data is then populated in Director Console and displayed in the form of line graphs and pie charts.

The Drill-down page also includes the tasks status of Director Console. It displays the total count of failed, completed, and pending tasks.

To monitor the visualization of an individual query in a pool:

1. Go to Dashboard.

2. Click Drill-down in the required Pool widget.

• The Failed Tasks, Completed Tasks, and Pending Tasks widgets include the data from the last seven days. The other widgets display the information available in the Fabric Proxy.

• The values of x and y coordinates change dynamically.

• When you select multiple LogPoint instances, each line in the line graph represents a LogPoint.

• If you hover on a particular point on a chart, a tooltip appears displaying the timestamp values in the chart.
