How can I monitor Linux SNMP without a MIB file?

How can I monitor Linux SNMP without a MIB file?

Performance Explorer provides the option of using a UCD-SNMP interface, if the package is configured on the Linux system under test:-

Go to PERFORMANCE EXPLORER | MONITOR | ADD DATA SOURCE | SELECT PREDEFINED | OPERATING SYSTEM DATA | LINUX | UCD SNMP.

Available defined measures are:-

Swap Size (Available),
Swap Size (Total),
Total Available Memory,
Total shared Memory,
Total buffered Memory,
Physical Memory size,
Average User CPU time,
Average Nice CPU time,
Average system CPU time,
Average Idle CPU time.

 

This is a predefined interface using OIDs specified in the Realtime.INI file for data measure collection.

When viewed in Notepad, you will see entries such as:-

S= Operating System Data\Linux\System (ucd snmp), SNMP,

M= SNMP:1.3.6.1.4.1.2021.4.4.0,
System\Memory\Swap Size (Available),
eAvgOnlyCounter, 0, kbytes, 0, 1, 2, 3, 4, 5, Available Swap Space on the host.

M= SNMP:1.3.6.1.4.1.2021.4.3.0,
System\Memory\Swap Size (Total), eAvgOnlyCounter, 0, kbytes, 0, 1, 2, 3, 4, 5, Total Swap Size configured for the host.

M= SNMP:1.3.6.1.4.1.2021.4.11.0,
