I'm sorry, but I don't see that increase at 5AM. From my point of view it starts at 4AM.GlueGuy wrote:Perhaps. But it was impossible to tell. When the problem happens, even the SNMP polls to the server itself (localhost) would have gaps in the RRD data.TheWitness wrote:Nope, not parallel. However, you may be having other issues (memory / diskI/O) maybe...
I changed the reportit cron job to run under "nice 10", which reduced the priority, and it seems to have mitigated the problem somewhat. The command is now:I still see the gaps in the graphs, but they are shorter duration.nice -n 10 /usr/bin/php /var/www/html/plugins/reportit/runtime.php -d > /dev/null 2>&1
I am now able to see what the load looks like. Backup starts at 1AM, then yum at 2AM. The reportit reports start at 5AM, and it looks like it increases the load significantly.
What about the I/O waits during that time?
Best regards
