What I did ...
Added host resource subagents in src/sonic-snmpagent to return the data for the supported OIDs in HOST-RESOURCES-V2-MIB
The OIDs can be found here: https://mibbrowser.online/mibdb_search.php?mib=HOST-RESOURCES-V2-MIB
In addition, the REDIS entry "MOUNT_POINTS | LastUpdateTime" shows up in the SNMP walk, when it should not, because there is no associated OID entry for this value. This entry was added for logging and consistency purposes.
How I did it ...
Added classes hrFSTable & hrStorageTable to handle the filesystem and physical memory related attributes for SNMP GET request
How I verified it ...
Added unit tests to verify the newly added OID implementation. The steps to run the unit tests can be found in azure-pipelines.yml in the sonic-snmpagent repo
Description ...
Add SNMP GET support and related unit tests for memory stats, filesystem and total disk usage table in ietf rfc2790 MIB
