NetXMS Forum

hi Token, thank you so much for your reply! The trick is very useful!

Hi All, I am trying to create a filtering script to check if a delay timer key has expired or not.  Is there any NXSL Class serves such purpose?

Here is what I am trying to achieve :-

1. Delay the email alert by 180 seconds if any node/interface is down [Done]
2. When the node/interface is up and the delay timer is still within 180 seconds, no email alert. Otherwise, an email alert on the node/interface is UP.

Any help is greatly appreciated!

Thanks for you information! Let me check!!

Up!

Hi All,

We have some heavy web page so we would like to monitor the load time of these pages from NetXMS server. Is there any plugin can do it?

Many thanks!

Hi All,

I found that a few Windows 2012 R2 server has sometimes this warning message "Too Many Communication Sessions Open - Unable to accept new connection". When it happens, I could not login or remote desktop to the server any more. I need to do a hard reset of the server. 

My NetXMS version is
Server 1.2.14
Agent: 1.2.17

Anyone has similar problem? How to fix it?

Any help is greatly appreciated!

hi All, after digging on the forum, I finally figured out how to do that. Basically, I use ExternalParameter to implement the traceroute checking function.  Here is what I did :-

1. Create a powershell script in a host, check_3hoptracert.ps1

2. In the nxagentd.conf, add this line

ExternalParameter = Check_3Hop(*): "c:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" "D:\netxms-agent\bin\check_3hoptracert.ps1" $1 $2 $3 $4

3. In NetXMS console, add a DCI per the screen attached.

Please make sure the AgentCommandTimeout specified in server configuration and exectimeout specified in nxagentd.conf are large enough to execute the script.

I hope this can help someone in the future. Thanks!

check_3hoptracert.ps1
===============
# This script is to check whether the first 3 hops of a traceroute is the same as the specifed ip addresses
# Return "OK" if same; otherwise "Changed"
#
# Usage : check_3hoptracert hostname 1st-hop 2nd-hop 3rd-hop
#
# Written by Pedro on 29/5/2014

# Get arguments
$hostname = $args[0]
$ip1 = $args[1]
$ip2 = $args[2]
$ip3 = $args[3]

# Run traceroute
tracert -d $hostname > c:\temp\tracert.txt

# Get 1st hop
$hop1 = get-content c:\temp\tracert.txt | select-object -skip 3 | select-object -First 1 | % { $_.substring(32,9); }
#write-host $hop1  " " $ip1
if ( $hop1 -ne $ip1 ) {  write-host "Changed"; EXIT 0; }

# Get 2nd hop
$hop2 = get-content c:\temp\tracert.txt | select-object -skip 4 | select-object -First 1 | % { $_.substring(32,9); }
#write-host $hop2
if ( $hop2 -ne $ip2 ) {  write-host "Changed"; EXIT 0; }

# Get 3rd hop
$hop3 = get-content c:\temp\tracert.txt | select-object -skip 5 | select-object -First 1 | % { $_.substring(32,9); }
#write-host $hop3
if ( $hop3 -ne $ip3 ) {  write-host "Changed"; EXIT 0; }

# The traceroute result is the same as specified
write-host "OK"
del c:\temp\tracert.txt
EXIT 1

Victor, thank you very much!

hi hksulja, have you found an answer to your question? If so, could you share with us? Thanks!!

hi all,

I just wonder if there is any monitor on the trace route result! What I want to do is if the predefined traceroute result is different from the real time traceroute result, an alert should be sent out.

Thanks!

Hi All,

In DCI, we can set the no. of poll before setting the threshold alarm. Is there any similar parameter we can set for Network Service?

Thanks!!
Pedro

hi Victor, where I can find the server log? Thanks!

Hi Victor, thanks for your reply! I use 1.2.5. Will update to 1.2.5

Thanks!

Hi SKYnv, I tried both "," & ";". Both doesn't work. Any idea? Thanks!

Hi All,

In the Action Configuration, is it possible to enter multiple email address in the recipient's address field?

Thanks!

Pedro

hi Victor, I found that if I use ip address, it works but doesn't work for domain name. I can do both ip address and domain ping in DOS prompt of the server. Is it normal? thanks!

Hi All,

I configured a node to do ping to another server by using icmp.ping("www.xyz.com") or icmp.ping(www.xyz.com). The value i got every time is 10000.

How to interpret the value? Anything wrong?

Thanks!

Pedro

Hi Victor, thanks for your reply!

The problem of this "unmanage" and "manage" approach doesn't work well for Switches because we unmanage those ports connecting to end user's computers to avoid generate alarms. When we use this approach "unmanage" and "manage", all the "unmanage" port will be reset and we need to set it again.

Any other approaches we can disable monitoring temporarily? Thanks!

Hi, we sometimes have maintenance of certain nodes. Just wonder if there is a feature that can temporarily disable monitoring of nodes so that we don't get alert message?

Many thanks!

hi Victor, after rebooting the server a few times, it seems working now but i didn't change anything. Thanks!
