Was: NSClient 1.0.8.0 Released Now: Monitoring NT event logs with Snare/Backlog, Swatch and passive checks.

[Stanley Hopcroft]

Dear Sir,

You may wish to submit a Nag FAQ about this clever and effective
way of monitoring NT event logs.

I take your point about scalability although surely swatch doesn't use
much does it ?

Is the problem with Swatch/Perl, or Nag being hammered via the command
queue.

If that is the case you may be interested in the performance
enhancements planned for Nag 2.0); otherwise, it may be possible to
turbo charge swatch by embedding a Perl interpreter in a C program (and
have that execute the Swatch logic).

Yours sincerely.
