One of my customers would like to extract the http header "last-modified" value, and transfer the result time into timestamp, so that they can count those the resources, say images, that are not been modified for more than one year? How can I help with this requirement? Shall I use "Operation Attributes"? Can "Operation Attributes" be used as Dimension in DMI?
Any comments are appreciated.
Solved! Go to Solution.
Do you have an ADS in your deployment? if it is the case you can play with the Opperation Attribute message field (on ADS), avoid the chosen parameter to count on the availability. I think that you can try to play too with the miscellaneus parameter, with care.
If you have an ADS available you can configure URL Monitoring to pull the specific HTTP header needed using either URL parameter groups or using the Dimensions, Metrics, and Attributes tab. If this is done correctly, you will create a new operation for each different "last-modified" value. New operation will look like "http://monitoredurl.com?lastmodifiedvalue".
Thanks for your reply.
I think the customer would like to extract the header value as a metric in DMI, so that they can do filter on this metric, say, they want to filter all operations that are not been modified since 6 months ago, can DCRUM do that, extract header value as DMI metric?
