Issue SNMP - SFOS SFOS 18.0.0 GA-Build321

Hello,

The OID for CPU load is 1.3.6.1.2.1.25.3.3.1.2.196608

I got this information from Zabbix, when scanned my Sophos XG 330 with Linux SNMP template. Sfos is Linux also.

snmpwalk -v 2c -c public 172.18.16.16 1.3.6.1.2.1.25.3.3.1.2.196608
HOST-RESOURCES-MIB::hrProcessorLoad.196608 = INTEGER: 5

For Memory load, the value is always 100%. The OID for memory load is 1.3.6.1.4.1.2604.5.1.2.5.2.0

snmpwalk -v 2c -c public 172.18.16.16 1.3.6.1.4.1.2604.5.1.2.5.2.0
SNMPv2-SMI::enterprises.2604.5.1.2.5.2.0 = Gauge32: 100

For Memory load, the value is always 100%. The OID for memory load is 1.3.6.1.4.1.2604.5.1.2.5.2.0

Thanks for sharing the CPU OID, it's seems to be the right value.

Same for me for the memory:
SFOS-FIREWALL-MIB::sfosMemoryPercentUsage.0 = Gauge32: 100

Well that's frustrating. Recently purchased LogicMonitor and was really happy about the monitoring for XG. Applied the update to 18 last night and now quite a few things are missing, just coming back with no data. Sorry Sophos but this just seems lazy. Don't you guys have a lab environment somewhere where you test things before pushing them out?? I would imagine there would need to be some internal monitoring of lab devices using snmp. How was this overlooked?

Ryan did you use the latest v18 MIB files? v17 MIBs wont work for v18

Hello All, 

Just an FYI, We have identified with the issue with V18 on Memory calculation and will be rectified in V18 Mr4. 

For more information regarding the memory calculation please refer KBA https://community.sophos.com/kb/en-us/135736 

That's likely the problem then. I just use the out of the box stuff from logicmonitor, which all worked fine on 17. I guess I'll have to hunt those down and figure out how to make it work in my copious amounts of free time.

This is the download file for v17 and v18 MIBs

Following will be addressed in v18 MR4.

• SFOS-FIREWALL-MIB::sfosMemoryCapacity.0 = Gauge32: 1 [ wrong Capacity]
• SFOS-FIREWALL-MIB::sfosMemoryPercentUsage.0 = Gauge32: 100 [most of the time if responds with 100%]
• In sync memory usage between Dashboard and SNMP. 

For CPU usage one can use: HOST-RESOURCES-MIB::hrProcessorLoad

Currently sfosSmtpService/sfosSSHdService status does not show correct value, will try to solve in v18 MR4.

So, we have to wait for the v18 MR4 version.

Is there any timeframe, when it should be available?

Thank you

Is there some technical reason these were changed/broken to begin with?
