I have a linux machine connected to a KEMP loadbalancer. I need to monitor/log the CPU, ram and network traffic. I've tried cacti but it doesn't seem to work properly - for example I've created device with the settings:
Hostname: <ip address of loadbalancer>
Host template: ucd/net SNMP Host
Downed Device Detection: SNMP Uptime
SNMP Version: Version 1
SNMP Community: public (which I have indicated at the KEMP loadbalancer snmp settings already)
1) Linux-memory usage
2) Load Average
Then I created a graph tree to show the Cacti graph template "Load Average" and "Memory Usage". However, there are no stats plotted on the graph (i.e. NaN).
In addition, I got Mib files from KEMP but it seems there's no feature on the cacti interface to upload our mib files. So I tried putting the mib files into /usr/share/snmp/mibs/. But do not know how or whether I should edit the snmpd.conf file. Is there a way to do this? I am new to Cacti, hope anyone can enlighten me on this please?
Pls let me know if you need more info.
