eG Monitoring
 

Measures reported by GFireMStatTest

By closely monitoring the reboot status, CPU usage, throughput and the I/O activity of each member, and comparing these metrics across members, you can quickly isolate resource-intensive members.

Outputs of the test : One set of results for each resource:member connected to the target GemFire server being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Is_running Indicates whether/not this member is currently running.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
No 0
Yes 1
Unavailable 2

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not the member is currently running.. The graph of this measure however, represents the status of a server using the numeric equivalents only - 0 or 1.

Active_executions Indicates the number of executions i.e., Continuous queries (CQs) that were active for this member. Number  
CPU_usage Indicates the percentage of CPU utilized by this member. Percentage  
Host_CPU_usage Indicates the percentage of time for which the CPU of this member's host was in use. Percentage  
Uptime Indicates the total amount of time for which this member was up and running. Seconds  
Total_regions Indicates the total number of regions present in the cache of this member. Number  
Average_reads Indicates the average rate at which data was read from the cache of this member. Reads/sec Compare the value of these measures across the members to figure out the most resource intensive member.
Average_writes Indicates the average rate at which data was written to the cache of this member. Writes/sec
Data_sent Indicates the rate at which object entry was destroyed from this region. MB/sec Compare the values of these measures across the members to figure out the member through which maximum amount of data is transmitted/received.
Data_received Indicates the amount of data received by the cache of this member. MB/sec
Clients_connected Indicates the number of client connections to this member. Number  
Total_locator Indicates the total number of locators in the GemFire server. Number This measure is applicable only for the ‘Summary’ descriptor.
Total_server Indicates the total number of backend servers communicating with the GemFire server. Number This measure is applicable only for the ‘Summary’ descriptor.
isRebooted Indicates whether/not this member is rebooted.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not the member is rebooted. The graph of this measure however, represents the status of a server using the numeric equivalents only - 0 or 1.
