Resetting the request histogram facility data to zero
The rhist reset request resets the histogram statistics.
Table 1 describes the keywords for the rhist reset response, in the order that they appear in the output. These keywords are used only when mmpmon is invoked with the -p flag. The response is a single string.
| Keyword | Description |
|---|---|
| _n_ | IP address of the node responding. This is the address by which GPFS™ knows the node. |
| _nn_ | The hostname that corresponds to the IP address (the _n_ value). |
| _req_ | The action requested. In this case, the value is reset. |
| _rc_ | Indicates the status of the operation. |
| _t_ | Indicates the current time of day in seconds (absolute seconds since Epoch (1970)). |
| _tu_ | Microseconds part of the current time of day. |
If the facility has been previously enabled, the reset request will still reset the statistics even if rhist off is currently in effect. If there are no mounted file systems at the time rhist reset is issued, the statistics are still reset.
An _rc_ value of 16 indicates that the histogram operations lock is busy. Retry the request.
