vmagent is a tiny agent which helps you collect metrics from various sources, relabel and filter the collected metrics and store
Can be used as a drop-in replacement for Prometheus for discovering and scraping targets such as node_exporter. Note that single-node VictoriaMetrics can also discover and scrape Prometheus-compatible targets in the same way as vmagent does.
Can add, remove and modify labels (aka tags) via Prometheus relabeling.
Can filter data before sending it to remote storage.
Can accept data via all the ingestion protocols supported by VictoriaMetrics.
Can aggregate incoming samples by time and by labels before sending them to remote storage.
Can replicate collected metrics simultaneously to multiple Prometheus-compatible remote storage systems.
Can save egress network bandwidth usage costs when VictoriaMetrics remote write protocol is used for sending the data to VictoriaMetrics.
Works smoothly in environments with unstable connections to remote storage. If the remote storage is unavailable, the collected metrics are buffered at -remoteWrite.tmpDataPath. The buffered metrics are sent to remote storage as soon as the connection to the remote storage is repaired. The maximum disk usage for the buffer can be limited with -remoteWrite.maxDiskUsagePerURL.
Uses lower amounts of RAM, CPU, disk IO and network bandwidth than Prometheus.
Scrape targets can be spread among multiple vmagent instances when big number of targets must be scraped.
Can load scrape configs from multiple files.
Can efficiently scrape targets that expose millions of time series such as /federate endpoint in Prometheus.
Can deal with high cardinality and high churn rate issues by limiting the number of unique time series at scrape time and before sending them to remote storage systems.

It does not guarantee the Snap is an official upload from the
upstream project.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Enable snapd
On Arch Linux, snap can be installed from the Arch User Repository (AUR).
The manual build process is the Arch-supported
install method for AUR packages, and you’ll need the prerequisites
installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
