[lustre-discuss] Lustre Monitoring metrics

[Masudul Hasan Masud Bhuiyan]

Hi,

I am very new to Lustre and  I am trying to get idea about the lustre
monitoring system. I have collected the stats from "/proc/fs/lustre".
Unfortunately I couldn't understand what does these data are actually mean.
I have tried to go through Lustre documentation and user guide to get
understanding of the data. But had no luck.

I will be grateful if you can help me to understand these log files. This
is a sample of stats for metadat server. But I am not sure how can I
interpret these stat. what does "mds_getattr"/mds_get_root/mds_quotactl
means?
