Process State Test

This test reports the total number of processes running on a system and the number of processes in the different process states - active, sleeping, runnable, zombie, stopped, etc. An unusually large number of processes in any of these six states can be an indicator of a problem. This test is disabled by default.

Target of the test : A Solaris, Linux, or HPUX system only

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every server being monitored

Configurable parameters for the test
  1. TEST PERIOD - How often should the test be executed.
  2. Host - The host for which the test is to be configured.
  3. DETAILED DIAGNOSIS – To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

    The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

    • The eG manager license should allow the detailed diagnosis capability
    • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total processes:

Indicates the total number of processes on the system.

Number

 

Running processes:

Indicates the number of processes that are currently running on a processor.

Number

 

Sleeping processes:

Indicates the number of processes that are waiting for an
event to complete.

Number

 

Runnable processes:

Indicates the number of processes that are waiting to be scheduled for execution.

Number

 

Zombie processes:

Indicates the number of processes that are in the zombie state - i.e., the process terminated, but its parent did not wait for it.

Number

 

Stopped processes:

Indicates the number of processes in a stopped state; A process can be in a stopped state if it receives a job control signal. Alternatively, a process that is being traced can also enter this state.

Number

 

The detailed diagnosis of the Running processes measure, if enabled, provides the Ids of the processes that are currently running, the user who initiated the processes, and the command used for invoking the process (see Figure 1).

Figure 1 : Detailed diagnosis of the Running processes measure

The detailed diagnosis of the Runnable processes measure, if enabled, provides the Ids of the processes that are waiting to be scheduled for execution, the user who initiated the processes, and the command used for invoking the process (see Figure 2).

The detailed diagnosis of the Zombie processes measure, if enabled, provides the Ids of the processes that are in a zombie state, the user who initiated the processes, and the command used for invoking the process (see Figure 3).

The detailed diagnosis of the Stopped processes measure, if enabled, provides the Ids of the processes that are in a stopped state, the user who initiated the processes, and the command used for invoking the process (see Figure 4).
