Hi,   We monitor the memory utilization on the basis of  Hardware Resources|Memory|Used % Metric. This gives us a warning when the used memory is more than 95%. Currently there's a violation and the server stats are as follows:   free -h                        total        used        free      shared  buff/cache   available Mem:            46G         39G        495M         67M        7.3G         23G Swap:           15G        524M         15G   Is there a way to monitor this available space with or without using a custom metric?   thanks, Hari Shree Joshi  ...

Can an extension be used to subscribe and read a file published on a JMS topic and also use data from that file as metrics?   ^ Post edited by @Ryan.Paredez to clean up the title of the post.  ... View more

How do I read the data on a JSON req received on AppD instrumented server and display that data on a dashboard? ... View more

I want to compare same metrics on different Servers (eg Calls per minute on a set of servers) and trigger an event if there is a big deviation amongst them.   If there are 2 metrics x & y. Then we can have 2 conditions: x/y>2 or x/y<0.5   This makes it difficult if there are more than 2 metrics, number of conditions increase exponentially.  Can anyone suggest any other approach.   Thanks, Hari Shree Joshi ...

For monitoring the JVM heap space we have health rules for the overall used% of the memory. This system works well but we have a few applications in which when routine jobs are being executed the old gen stays almost full for days with little space reclaimed up after each major GC and the new-gen keeps on being completely used and freed up between frequent GC cycles.  The heap space of such nodes gets used up to 97-98% at times before it is freed up and this creates a lot of unnecessary events on AppD.  How do we configure health rule for JVM heap space of such nodes so that fake alerts are minimized and OOM errors are prevented from occurring?     ...

Is there any way to trigger an event or a health rule for when a port is turned off or is down on an application server? ... View more

We are having issues with an app agent on one of the nodes of our instrumented application. Its status keeps dropping down to 0% and comes back up once it is reset. The support team advised us to upgrade the agent's version as the current version is outdated (v 4.0.4.0).   Now I cant find a relevant article in the documentation on how exactly it can be done. Do we need to install the app server agent again or is there a way to upgrade them through a wizard or something?    https://download.appdynamics.com/download/prox/download-file/sun-jvm/4.5.17.28908/AppServerAgent-4.5.17.28908.zip   Thanks.     ...

Out of all the servers we have configured on AppDynamics we have noticed that hard drive partitions or the volumes are not available on the sun servers. In other words, on the windows servers we can see the volumes as the Hard Disk Partitions but on the Sun Servers only one partition or volume by the name of /rpool is available. How can we have a better visibility of the mount points.   Also, on the windows server is there a way to dig deeper into the mount points?  ... View more
