Good day.
I have 1 web server, 1 db server, 1 rrd storage machine and few poller machines.
I use remote rrdcached. All graphs works fine, but…
when I open the page https://librenms/poller/performance I see: in section “Total Poller Time” all graphs load for a veeery long time, in section “Total Poller Time Per Module” the graphs cannot load at all. I I browser debug tool I see 504 gateway timeout. I open a separate link to the graph, for example, https://librenms/graph.php?type=global_poller_modules_perf&legend=no&from=1526983800&to=1590055800&height=60&width=113 and I see 504 error again.
In shell at this time I see next:
service php-fpm status
