22.4.20

Generate annotations for top 10 processes exceeding CPU and memory thresholds

Generate annotations for the top 10 processes that consume the most CPU and memory usage when they exceed specific thresholds. For more information, see Configuring-Linux-Monitor-Configuration and Configuring-Remote-Monitoring.

Automatic process monitoring

Automatic process monitoring has been added to the Linux processes monitor type to track the performance of processes based on specific thresholds and time intervals. For more information, see Configuring-Processes.

22.4.12

Support for process thread monitoring

Monitoring the process thread provides information about monitoring a multi-threaded process. It also helps to drill down to individual thread-level usage from a CPU and Memory perspective. For more information, see Configuring Processes.

Support for Linux OS configuration collector

PATROL for Linux KM publishes the configuration metadata to the server, which can be consumed for different products, for example HCO for capacity optimization. By using Linux OS configuration collector, users can select whether such enablement is required for their environment or not. By default, the Linux OS configuration collector is disabled.

22.4.10

Support added for monitoring new attributes

Monitor the following attributes of the NUK_Linux_OS (Linux_OS) and Memory (NUK_Memory) application classes in PATROL for Linux to monitor the worker nodes in a Kubernetes (K8S) environment.

NUK_Linux_OS (Linux_OS):

Total number of threads on the system (TotalNumberOfThreads)
Total number of processes on the system (TotalNumberOfProcesses)
Total number of FD count (TotalFDCount)
Allocated FD count (AllocatedFDCount)

Memory (NUK_Memory):

Percent of free memory (includes buffers-cache) (FreePCT)
Percent of memory pages used (includes buffers-cache) (Utilization)

For more information, see NUK_Linux_OS (Linux_OS) and Memory (NUK_Memory).

Support filesystem monitoring for K8S node

You can perform monitoring of the filesystem of the Kubernetes node. To monitor the filesystems from a K8S container, filesystems needs to be mounted in a container as read-only filesystems.
