Wafl-Check
Checks the filer for WAFL-related counters (e.g. consistency-points per second).
Usage
$ check_netapp_pro.pl Wafl -H <host> [-z cp_count] [-l 'wafl_avail_bufs generated CP'|...] [--help] [...]
Description
Checks the filer for WAFL-related counters like the rate of consistency-points (cp) per second. Since there are different counters for different types of cp you have to specify the label of the cp-type.
A list of supported counters and it's labels is printed via the --counter
switch.
The information gathered from this plugin corresponds to the CPty
-column of
sysstat -x 1
. The most interesting types are
back-to-back CP: The filer is having a tough time keeping up with writes.
deferred back-to-back CP: The back to back condition is getting worse.
Hint: Calling the getter with the switch --discover=counters
will explain each available counter in detail.
Simple Examples
