Multiple automatic inventory

netsysadmin · 2022-10-09 12:00:32

Hello all,

I have recently installed GLPI version 10.0.3 and also installed the native GLPI agent on 2 Macs to test.
I have 350+ Macs and 100+ Windows computers to manage.
1. By default, it seems that an inventory is only run "on load". Is this at boot time only?
2. On Macs, how can I have the agent run multiple times a day?
3. I would like to have the agents automatically run an inventory about 3 times a day everyday, but not all at the same time, but within specified time windows. For example, I would like the agents to run the 1st time once between 0900-1000, the 2nd time once between 1500-1600 and the 3rd time once between 2100-2200.

Is this possible?

Thank you

Hi netsysadmin,

by default, the agent runs every 23 to 24h. This is a setup you can change in GLPI.

There's no easy way to setup such accurate scheduling from GLPI: GLPI just tells agent at which frequency an inventory is expected.
But you can achieve your goal using computer scheduling system (crontab on unix, tasks scheduler on windows). With few scripting, you should be able to ask agents to wait for a random time from 0 to 3600 seconds, then force an inventory running such a command as root/sysadmin:
- on windows:

cd c:\Program Files\GLPI-Agent
glpi-agent --force

- on MacOSX:

/Applications/GLPI-Agent/bin/glpi-agent --force

Of course you need to have setup your agent before, otherwise also use "--server http://your-glpi/" option.

The simplest solution will still be to ask for an inventory every 8 hours to have 3 inventories by day, without any guarantee for the hour range.

Thank you, gbougard.
I will try that.

Just an FYI: the agent does not seem to be running every 23-24h on the 2 Macs that installed it.
How can I help you to troubleshoot this?

You can check/share "/var/log/glpi-agent.log" file.

Hi netsysadmin,

can you try the nightly build ? This should still fix the "can't parse retrieved dates in 'lastModified' field in XML file" error.
Get it there: GLPI-Agent nightly builds
