Thanks Sady. You're right, it's not a failover, so nothing probes those devices when their agent is down, but it is MUCH better to have them all just go grey until the agent is back online, rather than throwing a few hundred emails and then a few hundred more when the agent comes back online.

I have the Dude installed on a Windows 2003 Server, with two other servers set up as agents, to help distribute the probing of devices. Yesterday one of the agent servers went down, causing all the devices being probed by it to be listed as down and sending notifications for each service. Is there a...

I guess the easiest way I can put it is when a device does not respond to a probe, or responds bad information, but has not yet surpassed the threshold. For example, you create a ping probe to change to down and send a notification after 10 missed pings. If the probe notices 5 missed pings, it chang...

I'm trying to set up alerts for our Citrix server so we can be alerted whenever a user logs in. Using OID 1.3.6.1.4.1.3845.3.1.1.24.0, the string shows the most recent user logged in. By creating the probe: function: Citrix_Logon() - oid("1.3.6.1.4.1.3845.3.1.1.24.0") if(Citrix_Logon(), &q...

Is it possible to create a probe that compares the values of an OID on two separate devices? For example, NTP runs on the DCs right now, and I'd like to set up a probe to apply to certain servers that will query the time on the DC as well as on the server, and if there is a time difference of +/- a ...

I asked the same question a little while back. This seemed to be the best response:

The idea is to get an alert after a certain time period has past. In this instance I'm testing on the BES server. Any time a blackberry sends/receives an email it makes contact with BES, or if no messages are sent/received it periodically checks in. What I'm trying to accomplish is if it misses maki...

Yeah, I looked into the Rate function and figured it would be a big help, maybe I'm doing something wrong because any time I use that function the result is 0. I tried the same formulas you listed and each one with the Rate function just shows zero in the device label.

I'm trying to set up alerts for OIDs where the value is an octet string in Date Format. I'm having trouble with the format of how to set up the Probe to Alert after a certain time period has past. For example, BES has OIDs for "last interaction with device," but the octet string doesn't sa...

Thought I was onto something. If you do an SNMP Walk and right click on an OID, the option to create Data Source is there and when opening that you see the default is Gauge (Absolute Value) which implies to me that's the value of the counter. You can change that option to Delta to get the difference...

I think we're on the same page Sweetdude. The source code for the Data Source is below. What's racking my brain is that the source code for Probes is almost exactly the same, including the type, id, name, dataID, etc. The only real field that the Data Source has that a probe is missing is the data t...

Thanks for the tip Sweetdude. The algorithm from Fluke gave more stable numbers, yet they still didn't line up with the bandwidth usage reflected by the Dude or the Optiview. To get the bandwidth displayed in the links between devices the Dude uses the delta of sent/received octets multiplied by 8 a...

Good idea. Thanks for the work around Sweetdude.

This may sound like a stupid question, but does the Dude auto save the configuration or does this have to be done manually. Yesterday I installed two new switches in one of our TC Closets. When returning to the office I added them to the Dude and set up the Probes/Services on them. The server that h...

I've been using the Dude for about a month now and am very impressed, the Probe Thread has been very useful. One probe I am having trouble creating is for current bandwidth utilization, giving a notification at a ceratin percentage. Here's what I've done so far: Using the idea that (InOctets + OutOc...
