Hi Experts,
I have an application and it is scaled to 3 instances. Using Prometheus
I would like to scrape the metrics per each instance. for example i would
like to know how many number of http requests received per instance.
so i am exposing a metric like this requests_total {instance_id="xxxxxxx",}
9.0. finally i have specified the application url in prometheus config file.
* problem that i am facing*:
since the service is load-balanced, when prometheus scrapes it hits one of
the instance and fetch the metrics. eg: if prometheus hits instance one ,
at this point in time it will not have the details of instance2 and 3 and
hence there are
gaps in the graphs for this scrape interval.
to avoid the above situation, i need to use a persistence store to store
the metrics for all the instances and when prometheus asks that time i need
it fetch from the store.
Generally i would like to know what is the recommended way for this kind of
situation
Best Regards,
Hari
