Problem solved.

I extend snmp and create scripts in each server.
If matrix is ok then i get no alarm, else alarm appears.

Now i have problem with blinking statistics.For example i get values from each minute, almost all of them are "0", but sometimes i see other values.
That other values generate me false alarm.

So question - how to setup threshold to avoid false alarms.
Maybe something with delta? 

EDIT:
Solved, simple change number of samples works.

Hi.

I have another problem.

I want to monitor raid matrix of my servers.
I do some research and its possible tow ways.
1. extending SNMP - i find some extends scripts that are used in /etc/snmp/snmpd.conf, but don't have idea how to adjust that scripts for my request.
2. adding parameter in NetxmsAgent - none of parameters on my servers fits my request. Its possible to create new parameter, if yes - how?

Thx!

Hi again.

I have mess in my configuration, can't be for 100?% sure in what order i create things.
I setup repeating in threshold and it works great.

I fix my configuration using your advice and it works!
Problem SOLVED.

Thx Victor!

Part two.

I hope that helps.

First 5 screens.

I try do it in order.

Hi!

There is my working process:
1. Create 3 events - normal/warning/critical
2. Creating 3 event processing policys - normal/warning/critical and linked they with event. Policys have structure: IF my_event THEN Action generate/resolve alarm.
3. On nodes Data Collector Configuration in Threshold section i create two Thresholds - iIF my_value THEN my_event.

When i check node Last Value i see that my_value is greater that threshold, so alarm should generate.
Yesterday those alarm didn't work, but today suddenly alarmed me. I don't do anything (i think so).

Today i create new DCC parameter, same way as described above and setup values to generate alarms.
I see event exceeds my_value but don't generate alarms.

What i do wrong?

Thx!

Thx Victor!

I setup DCI origin and script with you instruction.
I run test script and get value about 0.25.

Then i setup  threshold:
Last pooled value: 1
> greater then: 0.2

Activation event:
SYS_THRESHOLD_REACHED

And apply changes.
But this settings don't generate alarm to me.
What i do wrong?

Thx!

EDIT:
I looked in into DCI history and all values are 0, how to "insert" value from script?
SOLVED: I changed Data type on Floating Point Number ;-)

EDIT TWO:
In Object Details of chosen node i see that threshold is exceed my value, but alarm is not generated.

Hi,

I would like to add new alarm node to Netxms.
Alarm shoud alert me when router have high percentage of memory.

I found three OIDs that i probalby use:

para1 = memTotalReal.0 .1.3.6.1.4.1.2021.4.3
para2 = 2memAvailReal.0 .1.3.6.1.4.1.2021.4.6
para3 = memCached.0 .1.3.6.1.4.1.2021.4.15

static:
max_ram_value = 0.9

My function shoud work when:
if
(para2 + para3) / para1 >= max_ram_value
then
SEND_ALERT

How to implemet tomething like that in Netxms?

Thx in advance!

Hello,

Thx for advice!
I add some objects manually but have to add a lot more, so i want try scripts.
I read about NXSL:BindObject, but i don't have idea how to use this function in script. More important - i don't know how to run script - can someone give a simple example?

Next, i have some VOIP gates in my subnet, can Network Discovery found this devices and add to my network?

Otherwise, is there any information about new devices founded by Network Discovery? Something like list of devices?

At last. How to visualize new devices i found? I would like to have map of that devices, is there easy way to do it?

Hi again,

I have little success - run Network Discovery in passive mode and find some nodes.
But there problems begins.
Founded nodes are in Entire Network label, and I want they to be in Infrastructure Services label.

So question - how to move nodes from one label to another?

Hey,

I run Active discovery today few hour ago but didn't see any effects yet.
I don't use filtering in this run and choose two subnets from my network.

I saw this script, but don't have any idea how to implement it - i find way to add it, but how force it to work?

I have idea to do it from other way - inject data to mysql database and try to read them by netxms. But still, only in project.

Thx for help in advance.

Hello,

I have new network and few nodes added manually.

I want to add rest of them. And its question to mus - how to do that?

I setup Network Discovery Configuration for passive mode, add some SNMP communities strings and run for few hours.
I'm not sure it is works for me - something shod appear in my NetXMS, right?
So my question is how to setup Network Discovery Configuration to find all devices - use active mode or not?

And how about external script? I can wrote IP Address list of devices i had in my network, but how implement it to NetXMS? Probably some scripts will be solution, but I'm green in it.

Sorry for my poor English,
Greetings!
