you might not need it - recent versions of NetApp's NetCache Appliances
provide all data through SNMP. I am preparing a new release of
mrtg-ntap-probe which will explain which SNMP OIDs to use. Here is a
short summary:
instead of "mrtg-ntap-probe -r hr" use the following OIDs:
Object Hitrate HTTP requests
ncHttpObjHitrate: 1.3.6.1.4.1.789.1.8.3.6.7.0
Bandwidth savings for HTTP requests
ncHttpBWsavings: 1.3.6.1.4.1.789.1.8.3.6.6.0
instead of "mrtg-ntap-probe -r url"
there are no equivalent values for the Instantaneous URLs and
the Average URLs per hour. Replace these with the total number
of HTTP requests and the number of HTTP requests that resulted
in a hit:
HTTP requests that resulted in hits so far
ncHttpHitRequests: 1.3.6.1.4.1.789.1.8.3.6.2.0
Total HTTP requests so far
ncHttpTotalRequests: 1.3.6.1.4.1.789.1.8.3.6.1.0
instead of "mrtg-ntap-probe -r urlftime" the following OIDs:
Avg Response time during last 60 seconds for all HTTP requests
ncHttpInstAvgRespTime: 1.3.6.1.4.1.789.1.8.3.6.12.0
Avg Response time for all HTTP requests
ncHttpAvgRespTime: 1.3.6.1.4.1.789.1.8.3.6.9.0
Your netcache.cfg file could look similar to this:
