i've written an SNMP plugin (attached) for Zeus Web Server. however, some of the metrics won't collect any data, even though i've enabled collection for them.
these metrics work:
Availability Uptime How many times a CGI script is executed per Minute How many times an NPH script is executed per Minute Number of requests served from the cache per Minute Number of requests streamed from disk per Minute How many times a local FastCGI is started per Minute
while these don't:
How many times the web server finishes handling a HTTP request per Minute Number of bytes the web server reads via HTTP connections per Minute Number of bytes the web server writes via HTTP connections per Minute
i don't see anything special about the metrics that don't work, and i've confirmed that correct values are being returned from SNMP. how can i find out what's wrong?
