Container Metrics

Applications Manager's Container monitoring tool ensures a seamless and efficient monitoring process by tracking a comprehensive set of container performance metrics:

Overall Health

Parameters	Description
State	Current state of the Container. Possible states are 'Running', 'Paused', 'Restarting', 'OOMKilled', 'Dead'.
Exit Code	Last exit code of Docker Container.
Error	Error message.
Started At	Latest start time of the Container.
Finished At	Last time the Container had stopped.
Restart Count	Number of times the container has restarted.

CPU and Memory Usage

Parameters	Description
CPU Utilization	The percentage of CPU utilized. In multi core machines, CPU utilization's value can be greater than 100.
Memory Utilization	The percentage of memory utilized.
Processor Count	Total number of processors available.
Memory Usage	Total memory used by the Container (in MB).
Memory Limit	Memory limit of the Container (in MB).

Network Stats

Parameters	Description
Bytes Received	Total number of bytes received by the Container interfaces.
Bytes Transmitted	Total number of bytes transmitted by the Container interfaces.
I/O Read	Number of IOs read to/from the disk by the Container.
I/O write	Number of IOs written to/from the disk by the Container.
I/O Total	Number of IOs completed to/from the disk by the Container.
tx-packets Dropped	Packets dropped while transmitting data.
rx-packets Dropped	Packets dropped while receiving data.

Memory Stats

Parameters	Description
Active File	Cache memory that has been identified as active by the kernel.
InActive File	Cache memory that has been identified as inactive by the kernel.
Active Anonymous	The amount of anonymous memory that has been identified as active by the kernel.
Inactive Anonymous	The amount of anonymous memory that has been identified as inactive by the kernel.
Cache	The amount of memory used by the processes of this control group.
Inevictable	The amount of memory that cannot be reclaimed; generally, it will account for memory that has been locked with mlock. It is often used by crypto frameworks to make sure that secret keys and other sensitive material never gets swapped out to disk.
Page Fault	Total number of page faults of the system.
Page Major Fault	Total number of major page faults of the system.
Page In	Each time a page is "charged" (added to the accounting) to a cgroup, pgpin increases.
Page Out	When a page is “uncharged” (no longer “billed” to a cgroup), pgpgout increases.

Configuration Metrics

Parameters	Description
Container Name	Name of the Container.
Container Id	Unique Id used to represent the Container.
Image	Base image used to create the Container.
Host Name	'Hostname to use for the Container.'
Process Id	Process Id mapped to the Container.
Ip Address	Assigned IP address of the Container.
Mac Address	Assigned Mac address of the Container.
User	User associated with the Container.
Created At	Time when the Container was created.
Command	Command used while running the Container.
Path	Path where the command will be executed.
Ports	Details of all the ports exposed by the Container.
Port Binding	Details of all the ports exposed by the Container and their mappings with the host.

"Standout Tool With Extensive Monitoring Capabilities"

★★★★★

It allows us to track crucial metrics such as response times, resource utilization, error rates, and transaction performance. The real-time monitoring alerts promptly notify us of any issues or anomalies, enabling us to take immediate action.

Reviewer Role: Research and Development

"I like Applications Manager because it helps us to detect issues present in our servers and SQL databases."
