<div class="PlainText">Dear Lustre administrators,<br>
<br>
what is a good command line tool to monitor current Lustre metadata and<br>
throughput operations on the local client or server? Up to now we had<br>
used collectl but this no longer works for Lustre 2.10.<br>
<br>
Some background about collectl: The Lustre support of collectl was<br>
removed many years ago but up to Lustre 2.7 it was still possible to<br>
monitor metadata and throughput operations on clients. In addition,<br>
there were plugins which also worked for the server side, see<br>
<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__wiki.lustre.org_Collectl&d=DwICAg&c=gRgGjJ3BkIsb5y6s49QqsA&r=23V5nhLj03jeTboyg6QveA&m=RpMjhssRJoiP3ANRP6Ze3_nBrliMMPOgQaewqEwRTn4&s=QmdmoNcRR5A0sOgiJimMo0KtZnc-ne44A4YY8aSWbuI&e=">https://urldefense.proofpoint.com/v2/url?u=http-3A__wiki.lustre.org_Collectl&d=DwICAg&c=gRgGjJ3BkIsb5y6s49QqsA&r=23V5nhLj03jeTboyg6QveA&m=RpMjhssRJoiP3ANRP6Ze3_nBrliMMPOgQaewqEwRTn4&s=QmdmoNcRR5A0sOgiJimMo0KtZnc-ne44A4YY8aSWbuI&e=</a><br>
However, it seems that there was no update for these plugins to adapt<br>
them for Lustre 2.10.<br>
<br>
Regards,<br>
Roland<br>
