[nv-l] NMAVAILABILITY and decoding availability data files

I am interested in getting availability data - simple node/interface -how long has an element been down. There is obviously no MIB variablethat will give you this.

On way is to process trapd.log looking for Node / Interface Up/Downevents and I'm sure some people have done this (anyone willing tocontribute such a script to the NetView Tivoli User Group website????).

However, if you set the environment variable NMAVAILABILITY=True thenyou get daily files created in /usr/OV/databases with names in the formavailData_yyyymmdd. These files were originally then fed into TivoliDecision Support and now are destined for Data Warehouse. I don't needall the functionality of these performance reporting programs - I justwant to make sense of the availability files.


Looking at the files, there seem to be 3 fields such as:
167772351    -1  1107083385
167772351     1   1107083647

The last field is time since the epoch. The 1 / -1 seems to representup/down, but how do I code the first field which obviously refers to thenode / interface in question??? I have a suspicion that the first digitis 1 for a node and 2 for an interface - other than that, I have toassume that there is some sort of translation from the NetView object idto the rest of that first entry. I've never seen this file documentedanywhere (but maybe I've just failed to find it?). Anyone know how todecode this?? It seems a shame to write my own trapd.log processingscript when NetView obviously already has a good mechanism to generateavailability data files.


Cheers,
Jane
