Not able to pick up CPU, Memory, Disk Information

Wed Aug 13, 2014 12:36 pm

I have installed Dude 3.6 on Windows 2008 R2. Discovery could find number of devices with services like NetBIOS, http, ping etc. but could pick up system information like cpu, disk, memory etc. only for the dude server itself and a Windows 2k server. For all other devices CPU, Disk, Memory services are appearing down. It may be a SNMP related issue!
Can anybody suggest if any specific configuration is required at Dude server end and the device end to solve this problem.
Thanks in advance.

Most likely the Windows firewall is blocking any queries of these services

In the Dude server the service has been allowed in the windows firewall.

Among the discovered windows servers, for which windows firewall is stopped and disabled and SNMP service is running with community public and right read-only, dude is not picking up system information.

For discovered layer 2 and 3 switches, it is picking up services like, ping, switch, router, http, telnet etc. but not picking system services like cpu, memory etc.

Manually SNMPwalk the device that you are trying to fix while simultaneously runing wireshark on the dude server and the server you are trying to monitor to determine if the packet is being sent, if the packet is being received, if there is a response being generated, and if the response is being received by the dude.

If the packet is not being sent run The dude as administrator.
If the packet is not being received check the firewall on the destination.
If the response is not being generated check the SNMP setup.
If the response is not being received in the dude server check the firewall here.

I need to monitor a HP switch.

The switch is appearing in the dude console but showing only http and telnet service up.

I need to monitor CPU, Memory, disk utilization and the network load on the ports of the switch through dude.

Please help if you can!!!!

Thanks!!!

It is going to be your SNMP configuration again. I don't own any HP switches but I guarantee you can get the information you just need to make sure SNMP is allowed and the community strings are correct. If the dude can reach the switch with Ping then just use SNMPwalk to verify that SNMP is correct.

Once you are certain SNMP is correct the location of various counters is dependent on the vendor. The CPU counter might not be in a "default" location so it is not likely to work but since interface counters are all based on the internet MIB those should work by just adding links and assigning the correct settings.

Search the probe thread for Cisco CPU and copy the function and probe but use the correct OID for HP then you should be able to track CPU usage.

NOTE: The dude downloads the routing table from routers so if you have a router with a giant number of routes (BGP) be careful to not let the dude read that router. Also most good routers will let you filter out what can be read through SNMP.
