NetXMS Support Forum

Is it possible to read out the Windows event log using the NetXMS agent? I found a topic
from last year stating that it was on the wishlist 

Hmm apearently this is a big problem 

When this "bug" occurs, no other events/alarms are executed.

This happens every now and then, not a big problem but still it would be nice to have this fixed.

When an alarm is triggered, and the alarm is terminated from the alarm viewer, it sometimes doesn't get deleted from the nodes' own alarm tab, if I try to delete it then it gives the following error: "Cannot terminate alarm: Invalid alarm id"

Hi

I'm trying to calculate the percentage of free ram using the NetXMS agent.

The system has 520093696 bytes of ram.
So I did this:

1)Went to transformation TAB of DCI
2)Put in the following calculation: ($1 / 520093696) * 100 
3)Set delta processing to: Keep original value.

This is the first time I've used this feature so talk slowly 
Thanks in advance.

Thank you victor, will test this in a minute. 
Also, I am still having the System.CPU.Loadavg read out at 0.000000, is there a solution for this as well?

Thanks again.

I did it!  For those interested:

Add one policy for the alarm with an unique alarm key
Add another policy for the opposite event to terminate the previous policy with the unique key
Add another policy for the opposite event to display the text: "this node was down blablabla"

Excellent! 

Sorry I am not sure what you mean.

Is this what you mean?

1)Make a rule for SYS_NODE_UP
2)At the alarm tab, I check "Terminate alarms" and put SYS_NODE_DOWN_%i there? (stopped using custom events)

Because this doesn't work 

-EDIT
This DOES terminate the SYS_NODE_DOWN error automatically but, how can I get it to terminate the error, as well as show in the alarm log: Node was down ,  or something like this?

I see! Thanks for your response as always.

I deleted all the already present policies from the "event processing policy editor" because I want to make
my own.

I also made my own types of events [NETWORK_PRINTER_DOWN] for example, which I gave an alarm message in my
native language.

As source for this policy I gave two printer nodes.

Now the problem:

When the node goes down, the alarm log tells me that the node is down like I configured it, but this error
does NOT go away when the node goes online again, it stays there untill I terminate the error, THEN my other
configured alarm log error shows up saying the node went offline.

I want to get NetXMS to automatically see that the node went back online, and DELETE the error saying that it is offline
so that the error saying that that node went offline stays in the log.

So basically:
1)Printer node goes down -> 2)I get an error saying that it went down [GOOD!] -> 3)The node comes back online -> 4)The error saying it's down stays untill I terminate it -> 5)Now I get the error saying that the node was offline earlier.

I want to make step 4 go automatically , i.e. eliminating the need for human interaction.

How do I do this?

Allright, great

The value returned by agent on hdd space:

System #1: Free:62.7GB     NetXMS reads out: 67G
System #2: Free:8.64GB     NetXMS reads out: 9284M

CPU load is at a constant 0.000000 value, which can't be right, the systems aren't idle.

I'll give you an example.

I add "entire network" to the source, but I want to select everything in the network BUT one printer. How would I do this without putting in everything except the printer to the source manually?

Do you understand what I'm trying to say?

I'm using the dutch version of windows on all machines.

It would be usefull to have an exclude function in the event processing policy editor "source" field 

Sorry, forgot to mention.

The agent is running on a windows XP pro 32Bit machine with SP2 installed.

I'm having some problems with several netXMS parameters, Using the 2.20 agent, console and server.


Parameters
system.memory.physical.free                                                                Works perfectly
System.uptime        Unsigned integer       60Sec interval              Not supported status
System.cpu.loadavg   Float             60sec interval         0.000000
Disk.Free(C:)            Unsigned int64         60Sec interval              Is inaccurate, reads 800MB, to 5GB too much

Just a few parameters I tried.
