Hello experts,
Through other community answers, we are advised that there is no table to query data from for stats.do and servicenow performance dashboard. But is there a possible script which can fetch this data specially for data displayed for memory.
We would like to be able to catch data that our instance is having high memory utilization if possible and be able to send us a notification when a certain memory is utilized before our instance throw an OOM error. Is this possible via scripts
Thanks in advance
Hi,
You can use this example to get the ball rolling:
var diag = new Diagnostics();
while (diag.nextNode()) {
var diagNode = diag.getNode();
var nodeName = diagNode.name;
var memUse = diagNode.stats['system.memory.in.use'];
var memFree = diagNode.stats['system.memory.pct.free'];
gs.info("Node name: " + nodeName + " Memory in use: " + memUse + " Memory % Free: " + memFree);
}
You can also refer to the UI Page: system_diagnostic_page for more information.
Then sort of take it from here.
The above is just an example to get you started.
Please mark reply as Helpful/Correct, if applicable. Thanks!
Thanks again for the help,
By the way, this line of code
var memUse = diagNode.stats['system.memory.in.use'];were able to get the memory in use, how were you able to come up with the system.memory.use, do you have any reference for looking through stats.do. Because for example we want to also display the allocated memory, how do we write it.
Or we want to get the other processor transaction values how do we modify the script for that.
Thanks
Hello,
Are these the one referenced in the script?
But when I looked for the content of it I can't seem to find how he was able to come up for which code to use to point for memory in use and what I can use for memory allocation.
