pagefile perf_counters only partially working

[tomstocker]

Hi all

Only the _Total perf counter are working. Agent2 v7.0, windows server 2022.

# zabbix_get -s hostname -k 'perf_counter["\Paging File(\??\c:\pagefile.sys\)\% Usage"]' -p 10050
zabbix_get [1916354]: Check access restrictions in Zabbix agent configuration
# zabbix_get -s hostname -k 'perf_counter["\Paging File(\??\c:\pagefile.sys\)\% Usage Peak"]' -p 10050
zabbix_get [1916719]: Check access restrictions in Zabbix agent configuration
# zabbix_get -s hostname -k 'perf_counter["\Paging File(_Total)\% Usage"]' -p 10050
14.957886
# zabbix_get -s hostname -k 'perf_counter["\Paging File(_Total)\% Usage Peak"]' -p 10050
15.463867

any idea why?

You have an extra backslash in the pagefile name. Without it works here:

PS C:\Program Files\Zabbix Agent> .\zabbix_agentd.exe -t 'perf_counter["\Paging File(\??\C:\pagefile.sys)\% Usage Peak"]'
perf_counter[\Paging File(\??\C:\pagefile.sys)\% Usage Peak] [d|25.936247173108551]

PS C:\Program Files\Zabbix Agent> .\zabbix_agentd.exe -t 'perf_counter["\Paging File(\??\C:\pagefile.sys\)\% Usage Peak"]'
perf_counter[\Paging File(\??\C:\pagefile.sys\)\% Usage Peak] [m|ZBX_NOTSUPPORTED] [Cannot obtain performance information from collector.]

Your're absolutely right, thanks for spotting. PEBCAK error :-)

(Get-Counter -ListSet * | select -expand PathsWithInstances | Select-String -Pattern "Paging")

\Paging File(\??\C:\pagefile.sys)\% Usage
\Paging File(_Total)\% Usage
\Paging File(\??\C:\pagefile.sys)\% Usage Peak
\Paging File(_Total)\% Usage Peak
