K8S monitoring index

Kubernetes itself monitoring

? Node resource utilization: general production environment dozens of node, hundreds of node to monitor? Number of Node: generally, you can monitor the number of node, because it is an example. How many projects a node can run, it also needs to be evaluated, and the overall resource rate is in what kind of state and value, so it needs to be evaluated according to the project, the resource utilization of the run, and the value, such as how many resources are needed to run another project.

? Number of Pods (Node): in fact, it is the same: how many pod can be run on each node, but by default you can run 110pod on a node, but in most cases it is impossible to run so much, such as a 128GB memory, 32-core cpu, a java project, an allocation of 2G, that is, 50-60 runs, the average machine, pod runs dozens, rarely more than 100s.

? Resource object status: for example, pod,service,deployment,job these resource status, do a statistics.

Pod monitoring

? Number of Pod (projects): how many pod have been run in your project, and what is the approximate profit rate, so that you can evaluate how many resources the project has run, how many resources it has, and how many resources each pod has taken up.

? Container resource utilization: how many resources are consumed per container, how much CPU is used, and how much memory is used? Application: this is the indicator of the application itself, which is generally difficult for our operators to get, so before monitoring, we need the developer to expose it to you. There is a lot of client integration, and the client library supports many languages. You need to let the developer do some development to integrate it, expose the indicators that the application wants to know, and then bring it into monitoring if the development department cooperates. Basic operation and maintenance is very difficult to do this, unless you write a client program, through the shell/python can not get the internal work from the outside, if this program provides API, this is very easy to do.
