Prometheus gathers metrics from specified targets at defined intervals, processes them using rule expressions, displays the results, and generates alerts.
Alertmanager processes and routes notifications to recipients via email, Telegram, Slack, and other integrations like PagerDuty or OpsGenie. It deduplicates, groups, and silences alerts while generating notifications based on rules defined in its configuration file.
Software Copy link
When selecting the Prometheus Alertmanager image in the Marketplace, Hostman will:
- Deploy Ubuntu 22.04 on your server;
- Download and install the latest versions of Prometheus and Alertmanager packages;
- Create the
/etc/systemd/system/prometheus.serviceand/etc/systemd/system/alertmanager.servicesystemd units.
Getting Started Copy link
To install the Prometheus monitoring system on a Hostman server:
-
Start creating a new Hostman server and select Marketplace → Prometheus Alertmanager.
-
Select server parameters. You can deploy this image with the minimum configuration; however, for smooth operation it is recommended to use 2 CPU cores, 4 GB RAM, and 20 GB disk space.
-
Finish creating your server.
Wait for the installation to complete. When the server is online, copy the IP address from the Dashboard tab. Now, visit your_ip_address:9090 in the browser, and you can start working with your Prometheus app.
