NetXMS Support Forum

I have a specific service that I want to monitor to see if it's up or not.

However the problem is, when it goes down (service stops) it's status stays at "0" and it just turns red, and I can't monitor it!

How do I get this DCI to switch to status 4 when it's down just like the internal status check?

Some questions about the parameters:

System.cpu.usage & System.CPU.Usage($1)

The system.cpu.usage readout is fine, but what will happen if I run this parameter on a node with multiple cores?  I know the system.cpu.usage($1) is used for multiple CPU'S but running this parameter on one of my dual core machines gives me incorrect information.   I'm just using "0" and "1" parameter for this, is this correct? and where can I find the core ID?

What's the deal? What parameter should I be using for monitoring CPU LOAD on DUAL CORE machines?   And which parameter for monitoring CPU LOAD on Hyperthreading machines?

Just a little confused 

Would this be possible to implement?  I know you are probably getting the
temperature for the HDD from S.M.A.R.T. but is it possible to get a processor temp readout for example?

Or even other components, chipset, VGA ?

Question about the parameter in PhysicalDisk.SmartStatus

The parameter page on the documentation page says the following: Zero-based HDD number on Windows

Exactly what is this? And how do I find out what number the target HDD has? 

Couldn't find this on Google 

It would be great to have a windows mobile 5-6 compatible version of NetXMS console, is this a possibility, or is this already on your wishlist?

Would be great to have 

1) Is it possible to delete items from the event log, and if not so, is it a good idea to implement this?

2) Is it possible to sort these events by clicking on the appropriate tabs?  so if I click on Source all the nodes are group together.

This would be very nice to have 

It would be very nice to have the option to print the alarm list, maybe add it in the context menu so you can just print the alarms you want to show people.

Is this an option?

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 

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.

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?

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

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.

I had to change the IP adress of my netXMS server to make it more secure, it's in another network now but it can still reach everything I want to monitor.

Now I have 2 problems,

1) Since I stopped the MySQL service + core service after having reinstalled NetXMS to restore my previous database the Core Service wont start (it starts, and immeidately stops).

2)The log file gives me the following error


[09-Apr-2008 13:07:47] Log file opened
[09-Apr-2008 13:07:47] Database driver "mysql.ddr" loaded and initialized successfully
[09-Apr-2008 13:07:47] Database is already locked by another NetXMS server instance (IP address: 192.168.70.9, machine info: TESTSERVER Windows Server 2003 Service Pack 2 Build 3790)


Is there any way to change the IP adress linked to the database? 

I added a node via internet (router with many interfaces).

One of the interfaces had the same IP range as my own lan (which I am also monitoring in netxms)
so naturally, this router interface was placed inside my own LAN "group"

Now I have deleted the router from the "entire networK" section, but when I delete the router
from my own LAN "group" it hangs on the "deleting object" screen and eventually it gives the error
"Unable to delete object: Request timed out"

Everything I try to do after this error occurs just hangs. For example when I try to open up the "alarms" screen
it times out, I have to shut down the console, log in again, and then I can work again.

What could be causing this?

In my LAN there are a lot of devices with the IP 192.168.70.*

Now when I add another node through internet or VPN, that node also uses 192.168.70.* range on their internal network interface. Now when I add this node, turn off automatic configuration polling, and delete all the interfaces but the one I want to monitor, netXMS has already placed the interface with 192.168.100.* in my internal network "group".

Is there any way to stop this from happening? This is a pretty big problem unfortunately. 

Example 1:

On one of the servers I'm monitoring (internal netwerk, just like example 2) the status check gives back a "4" when it goes offline. When I put it back online, netXMS doesn't notice this change, I can manually poll it, edit the config through netXMS .

What can be causing this? There is no firewall and no significant change since last time it worked 

/EDIT
On a workstation I've just added, this is working fine I am getting confused.

/EDIT2
I had a rule up in the event policy editor that said the following:

Source: [Computername] Event: SYS_IF_DOWN ALARM: [Hardcoded text] ACTION: [Send email]
Source: [Computername] Event: SYS_IF_up ALARM: [Hardcoded text] ACTION: [Send email]

When I deleted this rule, deleted the node and added the node again, everything worked perfectly, what am I doing wrong?


Example 2:

One of the printers with SNMP support i've added, when it goes offline it does not notice that the machine went offline, nor does it notice when it goes back online.  All the other DCI's via SNMP seem to be going properly and  they don't give any errors.

/EDIT
This node also has the "netXMS NAT adapter" listed as a network connection for some reason, can't find it in the documentation. Could this be the reason??

I'm using the 0.2.20 console, server and agent.

Is it possible to set a different retention time? I couldn't find it in the options and it would save me a lot of time! 

Thanks in advance

This feature would be very usefull as I only want to monitor one interface at a time.
For example holding the shift button to select multiple interfaces and delete them would be great.

Just an idea I had, see what you do with it 

I'm using the latest 32Bit agent on an XP32 machine, together with the 2.20 server and 2.20 console.

Using the agent to check available memory for example works great, but when I add certain dci's such as System.cpu.loadavg it doesn't retreive any data, causing the data of that DCI to stay at 1970, then when I try to delete this DCI it times out, and I have to shut down the console because I can't see anything in the last values tab of any object.

Then when I start the console again, it's stuck at "Synchronizing objects" and I have to restart the entire NetXMS server (stopping the service doesn't work).
