you have configured the relevant options within the ‘Details’ tab, you can
click on the SNMP polling tab:
main user journey for the SNMP Polling tab is:
Choose a Host (the Host must be added to Opsview Monitor and have the ‘SNMP:’ tab configured
Walk’ against the Host. This will list the OID’s of the Host, either
unformatted (18.104.22.168.2.5…) or formatted (using MIB’s).
OID and it will be populated into the OID field.
calculations using the Warning/Critical sections, i.e. if we are monitoring a
temperature, set the warning field to ‘>’ for the numeric comparison and the
value to ‘40’, and the same for critical but with a higher value. This means,
if the temperature goes above 40, set the Service Check to warning, if it goes
above X set it to critical.
submit changes and apply to one or more Host(s).
first step is to run the SNMP walk. You must select a host from the drop-down
selected, the ‘SNMP Walk’ button will be available to select. Clicking the ‘SNMP
Walk’ button will retrieve all of the OID’s from the Host in question, as
the OID’s are listed, you can choose to ‘Rescan’, which will re-discover all of
the OID’s on the Host. This is great in the event that you haven’t loaded the
MIB and have a lot of OID’s, as above. In this case, you can add the MIB’s and
rescan which should convert the numerical OID’s into a formatted, human- understandable version,
select an OID which requires monitoring – in the example below we are going to
monitor uptime, therefore we have clicked on the ‘Timeticks: (….’ Line:
modify the label, calculation rate and the warning/critical values as required:
Click ‘Submit Changes’ and
the new Service Check is created! See Section 22.214.171.124. Service Checks Tab for guides on how to add the newly-created Service Check
to a Host.
