Alerting on difference to historic value
Hi,
I'm new to LM (and Linux) and could use a pointer or three.
I'm attempting to monitor the health of a web application on a linux box. I'm retrieving values from a logfile in json format and have gotten as far as being able to graph the output but what I really need is to be able to compare the value of a particular datapoint from that file to the equivalent value from a week ago. If the value has increased by >15%, there's a problem and I need to alert on that. I've been able to configure a Device Metric Trend report which gives me these values but I'm not sure how to alert based on it. Could anybody advise?
thanks,
MH

·8 years agoyou "could" do this with a complex datapoint using groovy (https://www.logicmonitor.com/support/datasources/creating-managing-datasources/creating-complex-datapoints-with-groovy/) and using the get data rest API to retrieve the value you're looking for and do the math. It's complicated to do, but feasible.
This would be a good idea to raise in the feature requests, I believe others have asked for this same functionality.
