<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">Sorry for coming up with this never-ending story. I know that token management is mainly autoconfigured and even the placement of token manager nodes is no longer under user control in all cases. Still I would
like to monitor this component to see if we are close to some limit like memory or rpc rate. Especially as we’ll do some major changes to our setup soon.<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">I would like to monitor the performance of our token manager nodes to get warned _<i>before</i>_ we get performance issues. Any advice is welcome.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">Ideally I would like collect some numbers and pass them on to influxdb or similar. I didn’t find anything in perfmon/zimon that seemed to match. I could imagine that numbers like “number of active tokens” and
“number of token operations” per manager would be helpful. Or “# of rpc calls per second”. And maybe “number of open files”, “number of token operations”, “number of tokens” for clients. And maybe some percentage of used token memory … and cache hit ratio
…<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">This would also help to tune – like if a client does very many token operations or rpc calls maybe I should increase maxFilesToCache.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"> The above is just to illustrate, as token management is complicated the really valuable metrics may be different.<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">Or am I too anxious and should wait and see instead?<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">cheers,<o:p></o:p></p>
