vCenter VCSA (PhotonOS) 6.7 Memory : Cant get a single value
Bug report summary
When trying to monitor the memory of a vCenter (appliance VCSA) version 6.7, I got the message UNKNOWN: SNMP GET Request : Cant get a single value..
# /usr/lib/centreon/plugins/centreon_linux_snmp.pl --plugin=os::linux::snmp::plugin --mode=memory --hostname=vCenterIP --snmp-version='3' --snmp-community='community' --snmp-username='username' --authpassphrase='authpassphrase' --authprotocol=SHA --privpassphrase='privpassphrase' --privprotocol=AES --warning-usage-prct='90' --critical-usage-prct='95' --snmp-autoreduce
UNKNOWN: SNMP GET Request : Cant get a single value.
#
But all other checks are ok.
It's the same output with github plugin:
# /usr/lib/centreon/centreon-plugins/centreon_plugins.pl --plugin=os::linux::snmp::plugin --mode=memory --hostname=vCenterIP --snmp-version='3' --snmp-community='community' --snmp-username='username' --authpassphrase='authpassphrase' --authprotocol=SHA --privpassphrase='privpassphrase' --privprotocol=AES --warning-usage-prct='90' --critical-usage-prct='95' --snmp-autoreduce
UNKNOWN: SNMP GET Request : Cant get a single value.
#
I tried to use os::linux::local::snmp like explained in the issue #1370 but it doesn't exist, it's os::linux::local::plugin, and I don't know how to use it:
# /usr/lib/centreon/centreon-plugins/centreon_plugins.pl --plugin=os::linux::local::snmp --mode=memory --hostname=vCenterIP --snmp-version='3' --snmp-community='community' --snmp-username='username' --authpassphrase='authpassphrase' --authprotocol=SHA --privpassphrase='privpassphrase' --privprotocol=AES --warning-usage-prct='90' --critical-usage-prct='95'
UNKNOWN: Cannot load module --plugin.

I also had a look to the issue #1111 but it didn't help.

I can provide all snmpwalk output if needed.

Could you provide help for monitoring the RAM of VCSA?

Steps To Reproduce
See Bug report summary
Expected behavior
Memory usage.
You have done that procedure? https://github.com/centreon/centreon-plugins/issues/1370# Ok we need to check storage table.
No I didn't follow the procedure since it's not the official procedure from VMware, I don't want to break VMware's support.
I followed this procedure: https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.vcsa.doc/GUID-3695CE84-C6DF-497E-BA4E-2B341CC366C5.html

Hello, I have exactly the same problem for 3 month with only "check memory command" on my vcenter's vm and 4 qnap nas. For all others linux vm, all work fine. The problem began after update linux plugin package on my centreon server. Could you help me please ? Thanks
When we use the photonOS, we only have access to net-snmp package (https://github.com/vmware/photon/wiki/Downloading-Photon-OS). We don't have the vmware-snmp package. I think it's specific to esx and vcsa appliance. Could you provide the full snmpwalk ?
snmpwalk -ObentU -v 2c -c public 10.0.0.0 .1 > vcsa.snmpwalk
We got the snmpwalk elsewhere, feel free yo share yours anyway if you want us to test with your data.
You can use the new plugin: apps::vmware::vcsa::snmp::plugin
