GLPI Agent and disappearing Switch Network Ports

Musician82 · 2022-06-09 13:21:28

Hello There,

I'm are using GLPI 10 with GLPI Agent 1.2 (on Windows Server 2016). I have the following problem. I'm using the GLPI Inventory Plugin for getting all the information of our 11 network-switches (HP Aruba 48 Ports) via snmp , especially the network ports. The problem is, that in irregular intervalls, the network-ports, which has been already recognized at each switch, are not visible anymore. After an unspecific time, they appear again, but all the changes I made to specific ports, are away.

I did the following steps to setup all this:

1. Create new SNMP Credentials for our switches at "Administration" - "Inventory" - "SNMP Credentials"
2. Set the IP-Adressrange at "Administration" - "Inventory" - "GLPI Inventory" - "Network" - "IP Adress Range" and set the SNMP Credentials for that ip-adress-Range
3. Create new task at "Administration" - "Inventory" - "GLPI Inventory" - "Tasks" - "Taskmanagement" for Networkdiscovery of that IP Range
-> here I'm using the setting "start intervall: 30 minutes" and "number of agents: 1"
4. Create another new task for Networkdiscovery of that IP Range by using "Networkinventory SNMP"
-> here I'm using the setting "start intervall: 30 minutes" and "number of agents: 1"

Can anybody give me some advice, what I'm may doing wrong or how to solve this problem?

Thanks a lot!

Samuel

Hi.

I don't quite understand your problem. If you don't see switch ports in assets - most likely switch was added by fusioninventory. Delete it and allow GLPI Inventory to add it - the ports should be visible.

Hi,

for better understanding. The switches and also their Network Ports are being added as they should by the GLPI Inventory Plugin. The fusioninventory Plugin is not beeing used! The switchports appear correctly, but after an unspecific time, they disappear. After a while, they are beeing visible again. Whenever they disappeared, all changes I made to the ports are gone next time the ports appear again.

Hi Musician82,

what do you see in "Import information" and "Historical" tab for one device ?

Musician82 · 2022-06-10 09:22:17

Hi gbougard,

thanks for responding! I catched one switch (here with 8 ports) and in "Historical", it shows the following (this repeats regulary):

under "import information" it shows:

Date Rule Name
10-06-2022 09:10 NetworkEquipment update (by serial)
10-06-2022 09:10 NetworkEquipment update (by serial)
10-06-2022 09:07 Device update (by mac+ifnumber restricted port)

10-06-2022 09:07 NetworkEquipment update (by serial)
10-06-2022 09:05 NetworkEquipment update (by serial)
10-06-2022 09:05 NetworkEquipment update (by serial)

It seeams, that the Plugin creates all ports and five minutes later, it completely deletes all ports. Why? Can this behavior be changed? Shouldn't GLPI better just update the port-entries?

Thanks a lot!

Hi Musician82,

I'm not sure, but maybe NetInventory task is run 5 minutes before the NetDiscovery one. Maybe the agent log can clarify what's happen there. Can you check it and see what task were run at 9:05, 9:07 & 9:10 ? This is even odd you have so much "Last inventory date" updates in 5 minutes. I suspect a wrong task scheduling generating confusion.

Musician82 · 2022-06-10 10:02:41

Hi gbougard,

I think I might made a mistake, when configuring the agent. I actived modules "esx", "Collect" and "deploy", which are not being used - they all bring an error in the log. I will uninstall them. What I additionally recognized is, that the task "netinventory" runs into an error at 09:07:04. How can I avoid it and could this be the root of my problem?

I deleted the modules "esx", "collect" and "deploy" in the agent installation. Also, I disabled the task for Networkdiscovery for that IP-Range in GLPI Inventory Plugin-Tasks on glpi server. Now, the ports are not being deleted.
But the message "communication error: 500 Internal Server Error" when running the NetInventory, still turns up in logfile.

I couldn't find why.
Any ideas?

Hi Musician82,

this seems to be an error on server side. You should first check GLPI php-errors.log in case something goes wrong directly in glpi. Otherwise you'll have to verify you server configuration. Does it respect the requirements ?

Musician82 · 2022-06-13 15:12:33

Hi gbougard,

my glpi-server operating system is Cent OS 7, has 64 GB hdd, 8gb ram and 2 CPUs - so it should respect the requirements. But there are some errors on the php-errors logfile:

Do you know, what they mean and what I could do?

Thanks a lot!

gbougard · 2022-06-13 18:41:14

Have you upgraded to GLPI 10.0.1 & GlpiInventory plugin 1.0.1 ?

Musician82 · 2022-06-14 09:12:21

I upgraded from GLPI 9.5.6 to GLPI 10.0.0 and GLPI Inventory 1.01.

Should I upgrade to GLPI 10.0.1?

gbougard · 2022-06-14 10:21:00

Yes you should.

Musician82 · 2022-06-14 11:43:36

Hi gbougard,

I now successfully updated my glpi server to 10.0.1 and the errors in glpi-agent logfile are still there:
