Measures reported by VnxStatmonTest
The statMonService, when setup and started on a data mover, listens for requests for statistics related to that data mover from the Control Station and returns the statistics so requested. To monitor and report on data mover performance, the eG agent relies on the statMonService running inside the data mover. Therefore, if any test executed by the eG agent on a data mover fails or does not report measures, it would be a good idea to first check whether the statMonService is up and running on that data mover, before proceeding to troubleshoot. The VnxStatmonTest test performs this status check and reports the result.
This test queries every data mover in the VNX for File system for the current status of the statMonService and reports whether the service is currently running or not. If the service is active on a data mover, the test additionally reports the number of incoming network connections to that data mover and the maximum number of network connections that are permitted on that data mover. This way, the test also helps administrators figure out whether/not connection usage is optimal.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Service_status |
Indicates whether/not the statmon service is started on this Data Mover. |
|
If the statmon service is started, then this measure will report the value Yes. If the statmon service is not started, then this measure will report the value No.
The table below lists the numeric values that correspond to each of the states mentioned above:
| State |
Numeric Value |
| Yes |
1 |
| No |
0 |
Note:
Typically, this measure will report the States indicated in the table above as its values. However, in the graph of this measure, the States will be represented using their numeric equivalents only - i.e., 0 and 1. |
| Current_conn |
Indicates the current number of network connections to this data mover. |
Number |
|
| Conn_usage |
Indicates the percentage of permitted connections that are currently in use. |
Percent |
A low value is desired for this measure. A value close to 100% indicates that too many connections have been established with the data mover. Compare the value of this measure across data movers to identify which data mover will very shortly be rendered inaccessible because of a lack of connections. You may consider pre-emptively resetting the maximum number of connections of that data mover to avoid such an outcome. |
| Max_conn |
IIndicates the maximum number of network connections that can be established with this data mover. |
