Solve the problem that pushgateway data will be overwritten by multiple push

problem

Multiple client, To the same station pushgateway When pushing data , Use the same job name , You will find that there is only one left client The data of , Others will be covered

Using language python

analysis

I found out by grabbing , All data has been pushed to 9091 port , So the exclusion is some client Push questions

Code

push_to_gateway(pushgateway_url, job=job_name, registry=registry)

It is equivalent to pushing to metrics/job/job_name

Question why

Push indicators are managed by group , It is identified by the grouping key of any number of labels , Generally speaking, there are Job Follow instance, Only specify when pushing Job Words , Will miss a few server The pushed data is treated as the same group of data , Coverage occurs

Therefore, the unique identification of this batch of data should be added to the grouping identification , That is, the push link should specify the unique storage location for this batch of data , Similar to the concept of house number . Only job It's equivalent to pushing them to the same position .

solve

Pushed to the metrics/job/job_name/instance/id that will do

Here we can push to metrics/job/job_name/client/client_name

reference python Usage of Library

  Change to the following code to successfully push

push_to_gateway(pushgateway_url, job=job_name, registry=registry,grouping_key={"client":client_name})
