Alternatively, while still using v3.x:
Create a batch file that stops & starts the dude service, and schedule it to run daily (at some point at night).
I have been doing this for the past couple of years without issues. Keeps the memory footprint low without any other side effects.

reporting v3 bugs will not help

Agreed.
However, reporting workarounds for users not yet having had an opportunity to go to 4 beta is still seems helpful

Probably the Dude is a single threaded program, so it will not use more than one (logical) CPU.

Simply use the built in function if you want to display just the CPU usage on the device label. Add this to the Appearance --> Label of your device:

Installed, ok. But also configured properly? Security setup correctly? Community strings? Etc.?

winkelman

By default you perform the SNMP walk from the PC you're working on. However, for The Dude to work properly, the SNMP needs to work from the Dude Server. When doing the SNMP walk (to test), you can change 'from local workstation' to 'from Dude server'. Does that work?

winkelman

Is SNMP enabled on your servers? And configured? Probably not... First look into that.

winkelman

That's a known bug.

If you have a recent backup, use it (after completely reinstalling The Dude afresh). No backup? Wait for the bug fix in the next release.

winkelman

If you simply add

[oid_column("1.3.6.1.2.1.25.4.2.1.2")]

to the appearance of your device, it should list all running processes of your device on the device label. Now you can easily check if a) the SNMP query works and b) if your process is actually listed.

winkelman

I would assume the SNMP tab is populated simply by querying for some specific OID's (or arrays of OID's). All in all The Dude might request some tens of OID's (perhaps a few hundred) every 20 seconds or so. Should not be any problem. In the end: I do not know the inner workings of The Dude. But popu...

winkelman

Yes, that should possible with SNMP and some clever use of Dude functions. It would work something like this: find the array in SNMP that stores the running processes (that's this one: 'oid_column("1.3.6.1.2.1.25.4.2.1.2")'). Note the index (position) 'your' process in the array. Then look...

Why would the Dude be SNMP walking your switches all the time? The Dude will only request specific SNMP OID's from your devices (only those you've told The Dude to monitor). Probably cpu, mem, some link stats, that sort of thing, plus specific SNMP queries you yourself might have created. None of th...

winkelman

Can't you manually start The Dude Server service (in Windows, Administrative Tools, Services)? Or check there what might be the problem?

winkelman

Can you 'SNMP-walk' the PC from the Dude? If not: first fix the SNMP service/settings on the PC and The Dude (did you set a community name, etc.?). If so: tell us exactly what you entered in your probe.

winkelman

You could just reinstall The Dude and import a recent backup. (You do make backups, don't you?)

winkelman

But

Can you send mail using that SMTP server with some other program on the Dude machine?

winkelman

Does your SMTP server accept connections from The Dude machine? I can imagine SMTP services (by default) not accepting any connections (to prevent becoming open mail relays).

Can you send mail using that SMTP server with some other program on the Dude machine?

winkelman

Gaps in graphs could simply mean the device has (temporarily) not returned answers to The Dude's SNMP queries...

Not to say The Dude does not behave quirky sometimes...

winkelman

Dude v3 will have oid_raw() and oid_column_raw() functions that will return
raw, unformated values of oids.

Ah, great!

How to graph uptime ('timeticks') in higher 'resolution' than days?
