## Scraping big number of targets
|

|
||||
A single `vmagent` instance can scrape tens of thousands of scrape targets. Sometimes this isn't enough due to limitations on CPU, network, RAM, etc.
|
||||
In this case scrape targets can be split among multiple `vmagent` instances (aka `vmagent` horizontal scaling and clustering).

In this case scrape targets can be split among multiple `vmagent` instances (aka `vmagent` horizontal scaling, sharding and clustering).
|
||||
Each `vmagent` instance in the cluster must use identical `-promscrape.config` files with distinct `-promscrape.cluster.memberNum` values.
|
||||
The flag value must be in the range `0 ... N-1`, where `N` is the number of `vmagent` instances in the cluster.

The number of `vmagent` instances in the cluster must be passed to `-promscrape.cluster.membersCount` command-line flag. For example, the following commands
