Add support for Dell switches running current Dell OS versions (9.14+)

Looking to add support for Dell switches like S4048-ON, S4048T-ON, S3148, S3124 running FTOS 9.14+ which have moved away from working with Force10 MIBs.

  • CPU utilization (missing on all above mentioned swithces)
  • Memory util. (missing on all above mentioned swithces)
  • Power Supply Unit status (missing on all above mentioned swithces)
  • Fan Status (missing on all above mentioned switches)
  • Detect serial number properly. [This is because Dell is special and uses Service Tag instead] (missing on Inventory tab (says NA))
  • Detect optic interfaces and grab Tx/Rx signal strength, temperature of optic, etc. In the hopes of graphing the signal strength under the “Health” page for the device or similar area.

Improvements needed in current Librenms detection:

  • Dell switched their S-Series switches away from Force10 to using Dell specific MIBs somewhat recently and as such the following needs to check DELL MIBS instead of F10-S-SERIES-CHASSIS-MIB
 Dell S Series ChassisSNMP['/usr/bin/snmpbulkwalk' '-v2c' '-c' 'COMMUNITY '-OQUs' '-m' 'F10-S-SERIES-CHASSIS-MIB' '-M' '/opt/librenms/mibs:/opt/librenms/mibs/dell:/opt/librenms/mibs/f10' 'udp:HOSTNAME:161' 'chStackUnitCpuUtil5Sec']
  • an SNMPBULKWALK oddity i noticed when polling my in-production S4048-ON, I got the following error, as such the below example (in the Optics detection section) are excerpts of snmpwalk on the S4048-ON, and the attached snmpbulkwalk is from S4048T-ON which has no optics.
