NetView NT 5.0A - Availability Tracking
Since re-installing NT, MS SQL and NetView I can now get availability stats - I
think I may have had ODBC problems before.
I still have two questions however, and hope someone can help me out. For nodes
that have no SNMP support availability tracking is working exactly as I expect.
It logs the information of node down/up events, when they occurred and how long
they occurred for each node. It then also calculates percentage up/down time
for the node.
My first question regards node which have SNMP support.
1) For those nodes that support SNMP all I get out of availability
tracking is the value of the MIB2 system variable, sysUpTime. This value only
indicates the length of time for which the SNMP agent in the device has been
available. Consequently, there is only ever one entry in the availability table
for an UP status which shows how long the SNMP agent has been up since it's
last restart and therefore the percentage of uptime is always 100%. This cannot
be correct - how can I get the availability tracking for SNMP nodes to simply
track node up/down events as it does for non-SNMP nodes?
2) My second question is regarding availability tracking incorporating
service level agreements. My customer wants to calculate percentage up/down
time only within agreed service hours (in their case 7:30am until 5:00pm). I
told them they could use write their own SQL queries to query the SQL database
tables. If however they could view the source for the GUI program which
produces percentages for all hours and they could then customize this it would
obviously save them a lot of time. Is it possible to view the source/SQL query
for the GUI option ?
