<div>Several processes per CPU core, probably? It’s a lot.</div>
<div><br>
</div>
<div>But there’s a lot of environmental and configuration dependence here too.</div>
<div><br>
</div>
<div>Why not look at how many you have running currently when Lustre is set up and set the limit to double that? Watching process count isn’t a good way to measure load anyway - it’s probably only good for watching for a fork-bomb type thing, where process
count goes runaway. So why not configure to catch that and otherwise don’t worry about it?</div>

<div>Hi,<br>
This question is I guess not truly answerable because it is probably very specific for each environment etc. but I am still going to ask it to get a general idea.<br>
<br>
</div>
We started testing monitoring using Zabbix, its' default 'too many processes' threshold is not very high, so I already raised it to 1024 but the Lustre servers are still well over even that count.<br>
<br>
</div>
So what is a 'normal' process count for Lustre servers?<br>
</div>
Should I assume X processes per client? What is X?<br>
<br>
</div>
Thanks,<br>
</div>
Eli<br>
