For sending alerting notifications vmalert* relies on Alertmanager configured via -notifier.url flag. Recording rules results are persisted via remote write protocol and require -remoteWrite.url to be configured. Vmalert is heavily inspired by Prometheus implementation and aims to be compatible with its syntax.
A single-node or cluster version of VictoriaMetrics are capable of proxying requests to vmalert via -vmalert.proxyURL command-line flag. Use this feature for the following cases:
for proxying requests from Grafana Alerting UI;
for accessing vmalerts UI through VictoriaMetrics Web interface.
Integration with VictoriaMetrics TSDB;
VictoriaMetrics MetricsQL support and expressions validation;
Prometheus alerting rules definition format support;
Integration with Alertmanager starting from Alertmanager v0.16.0-alpha;
Keeps the alerts state on restarts;
Graphite datasource can be used for alerting and recording rules. See these docs;
Recording and Alerting rules backfilling (aka replay). See these docs;
Lightweight and without extra dependencies.
Supports reusable templates for annotations;
Load of recording and alerting rules from local filesystem, URL, GCS and S3;
Detect alerting rules which don't match any series.

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.
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:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install vmalert, simply use the following command:
sudo snap install vmalert
Browse and find snaps from the convenience of your desktop using the snap store snap.
