Hi All,
How to monitor an NFS file system Mounted RHEL7 system using appdynamics?
I have tried using monitoring NFS using "AppDynamics Extension for Linux Monitoring"
I have configured based on the documentation but unfortunately, I do not see the NFS share
using machineagent-4.4.3.1214.
I am getting the following error:
INFO MetricWriteHelperFactory - The instance of MetricWriteHelperFactory is com.appdynamics.extensions.MetricWriteHelper@4da9ced9 [Monitor-Task-Thread3] 23 Aug 2019 12:50:21,893 ERROR NFSMountMetricsTask - Exception occurred collecting NFS I/O metrics java.lang.NullPointerException at com.appdynamics.extensions.linux.NFSMountMetricsTask.getMountIOStats(NFSMountMetricsTask.java:173) at com.appdynamics.extensions.linux.NFSMountMetricsTask.run(NFSMountMetricsTask.java:66) at com.appdynamics.extensions.MonitorThreadPoolExecutor$2.run(MonitorThreadPoolExecutor.java:102) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) [Monitor-Task-Thread2] 23 Aug 2019 12:50:22,049 ERROR FileParser - Failed to read CPU metricStats java.lang.NullPointerException at com.appdynamics.extensions.linux.FileParser.getStats(FileParser.java:65) at com.appdynamics.extensions.linux.Stats.getCPUStats(Stats.java:91) at com.appdynamics.extensions.linux.LinuxMetricsTask.run(LinuxMetricsTask.java:58) at com.appdynamics.extensions.MonitorThreadPoolExecutor$2.run(MonitorThreadPoolExecutor.java:102) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) [Monitor-Task-Thread2] 23 Aug 2019 12:50:22,050 ERROR Stats - Exception fetching CPU metricStats java.lang.NullPointerException at com.appdynamics.extensions.linux.Stats.getCPUStats(Stats.java:93) at com.appdynamics.extensions.linux.LinuxMetricsTask.run(LinuxMetricsTask.java:58) at com.appdynamics.extensions.MonitorThreadPoolExecutor$2.run(MonitorThreadPoolExecutor.java:102) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
