Make it a script threshold. Then compare the value to the result of time() function. https://wiki.netxms.org/wiki/NXSL:time

Hi Victor It seems as if it was the agent on the node. I moved DCI's to another node and it worked again. I suspect it is something to do with the server node. Regards

By request here is more in detail Under event configuration i have setup events named Alarm for all the severity levels the message is what you see in the alarm browser. Event policy is set to execute xmpp and action snd_alert on these events The action then runs command on the node via the agent and what the action sends to the node agent is returned by the script snd_alert snd_script: body = "snd_alert"; if ($event->parameters[2] == "SQLServer:General Statistics: Processes blocked") { body .= " sql_locked"; if ((localtime()->hour == 13) && (localtime()->min < 15)) { body .= " delivery_journal"; } } if ($event->parameters[2] == "SQL Deadlock") { body .= " sql_deadlock"; } if ($event->parameters[2] == "MD5 hash check for unchanged file") { body .= " breadcrumb_files"; } return body; In the agent configuration is: ActionShellExec=snd_alert:/alert_sound/alert.sh $1 $2 Scenario: On the DCI named SQL Deadlock there is a threshold that triggers if the polled value is greater then 3. This triggers the Alarm Major severity The policy on Alarm Major triggers the action snd_alert The action snd_alert runs script snd_alert The script has statement for SQL Deadlock and the return string will be "snd_alert sql_deadlock" The first value is the action to run on the node agent "snd_alert" the second value is the first parameter The agent will then run: "/alert_sound/alert.sh sql_deadlock" For me this runs a wave file named sql_deadlock on the dashboard TV and inserts the event in a local db You can add more parameters by adding $3 $4 etc on the action and returning more values via the script.

Hi There This is probably a easy one but i need help.  What is the easiest way to monitor the state of scheduled tasks on a Windows server? I need to monitor if it ran successfully or not. Regards

I suppose currently it's not possible with tables - you need something like "diff" for table row but table thresholds operates only on current table value. You can try to use instance discovery - it will create DCI for each OID, and then you can use diff threshold to detect individual OID value change. Best regards, Victor

Hi Alex I just created node 1036. and 3 dci's: DCI IDs's: 517, 534, 535. But cant seem to find the table where values are stored.  I have been looking in all your tables described. I can only find the first dci's value in idata_1036. But not the other 2 values. Please assist. Regards

If you use context menu it will extract currently selected DCIs. You can also use "export all" option in view menu (in top right corner). Best regards, Victor

Hi Victor That was it.  I left out the instance in thresholds.  I initially thought that it would use the instance name in the parameter description. But all is good now. Thanx again for your speedy replies Regards

Hi There Thanx for the info.  I actually did it the exact way as you suggested.  Funny thing you would not believe how unstable 8.8.8.8 is. Node actually goes down alot with my internet still working.  Regards

Hi, there is a tutorial on sending notification: https://wiki.netxms.org/wiki/How_to_send_e-mail_notification_when_disk_space_is_low - just skip data collection and threshold part and use SYS_NODE_DOWN event in event processing policy. Best regards, Victor

Thanx for the speedy reply. I actually found what my issue was. i was using the gmtime function and just changed to localtime and it works 100% now I used basics here but nonetheless it works  day = localtime($1)->mday; mon = localtime($1)->mon+1; year = localtime($1)->year; hour = localtime($1)->hour; min = localtime($1)->min; return day."-".mon."-".year."/".hour.":".min; I could have just added a variable t = ($1) to make it even easier. Thanx for the advice and putting me in the right direction.

Hi Victor Thanx so much for your help.  It put me in the right direction. My script i compiled was: t = ($1); day = gmtime(t)->mday; mon = gmtime(t)->mon+1; year = gmtime(t)->year; hour = gmtime(t)->hour; min = gmtime(t)->min; return day."-".mon."-".year."/".hour.":".min; This gave me an output in the following date format: 14-1-2016/14:29 DD-M-YYY/HH:MM I also struggled a bit but remembered to capture string data and not int. I find this helpful for monitoring last modified date and time (which is highly important in my company for some files). Just wanted to say thanx to Victor.  Really appreciate your help. Regards Duane

really helpfull, thanks
