[SOLVED] disk full

lelunicu · 06-18-2019, 07:10 AM

hi,
in our company i know that we use treshold to generate alarm when disk in every linux server reach 80%.if i execute crontab -l there is empty file on every server.WE have zabbix client installed on server.I think the zabbix server is configured -when the disk is 80%full in every server then the alarm will be generated.Is this right?

Sorry, but your question is extremely non-clear. Can you please explain in greater detail what you are running with cron, what software generates alarms when you reach a certain disk threshold, and why Zabbix has anything to do with all this?

in every linux server when every disk reach 80% full will be generated an alarm.
I try to see where is the script that check the disk and generate the alarm.
I searched to see if in crontab is something but is nothing.
Every server has zabbix installed-so i think that zabbix server is configured to ask from zabbix client in every server if the disk reach 80%.
Is the above possible because the crontab in every server is empty?

yes, zabbix can do that, but we have no any information about how is it configured, so it is possible, but we are not sure.

Is this a case where you're exploring servers which were configured by someone else? Is that someone else available to just ask? It's probably far more efficient to ask the person or persons who configured that server, versus asking here. As pan64 mentions, zabbix is capable of that, but there are also some variety of other methods which can be used to accomplish the same feat. Bear in mind that someone earlier may have envisioned using zabbix for that, or something else, installed it, and then never used it. Or it is there for some other purpose, and also could be there for some old reason where it is no longer used or needed. Therefore trying to reverse engineer it may just be frustrating.

Another option is to look at the actual log files which are indicating that you've reached a threshold, determine the owner of them, determine the directory location for them, and see if this information leads you to a better conclusion.
