Mongodb calls always shows 0ms

[CommunityUser]

we have 3.8.0 version of the agent installed in all our machines. I see mongo db sppear in the appd UI but all calls to it shows only 0 ms. 

WHen I look at the very slow snapshot I do see calls to mongo db from the driver slow.

can someone please clarify this?

Hi,

Can you provide screenshots from controller UI depicting the issue to assist you further ? and also screenshot from slow db/remote calls screen in controller UI with higher time trend select this helps us to see what is the max ART ms reported for the backend in question :

Here are some screenshots.  I know mongo is not responding with 0ms response times but AD never shows us the true response time unless we click into a slow transaction snapshot and view the "hotspots".  We'd really like to be able to look at trends, etc with in AD as our apps use MongoDB.

Hi,

Can you send the exported app xml of "PROD-2" app (Actions -> export from app dashboard) and also screenshot with "Max" metrics selected from metric browser -> Backends -> expand <mongo db.find vehicle split) -> add response time metric to graph at right panel for time range last 2 hours and send the screenshot

Also provide screenshot from Troubleshoot -> slow db response times & remote services with 2 hours in view from UI,

in provided screenshots we are referring to aggregated metrics and 1 snapshot , Also confirm are all the calls to Business transactions are captured in UI, we see only Mongodb.find api is there other apis being called as well?

ALl of our calls to mongo are under one BT which is find, we didnt define anything on our own  this is what was autodetected.

We are 99% reads system so most of our calls to mongo are queries

Can you provide screenshot from metric browser similar to one provided to us with only Max checkbox selected, and also confirm by any chance the data is retrieved from cache here , if this is not the case, please send the zipped version of <agent_install_dir>/logs for our review with logs collected in debug mode (change logging level from info to debug in <logger level="info"/> in log4j.xml at <agent_install_dir>/conf/logging path
