Application summary
VictoriaMetrics is a fast and scalable open source time series database and monitoring solution.
Description
VictoriaMetrics is a free open source time series database (TSDB) and monitoring solution, designed to collect, store and process real-time metrics.
It supports the Prometheus pull model and various push protocols (Graphite, InfluxDB, OpenTSDB) for data ingestion. It is optimized for storage with high-latency IO, low IOPS and time series with high churn rate.
For reading the data and evaluating alerting rules, VictoriaMetrics supports the PromQL, MetricsQL and Graphite query languages. VictoriaMetrics Single is fully autonomous and can be used as a long-term storage for time series.
VictoriaMetrics Single = Hassle-free monitoring solution. Easily handles 10M+ of active time series on a single instance. Perfect for small and medium environments.
Getting started after deploying VictoriaMetrics Single
Config
VictoriaMetrics configuration is located at /etc/victoriametrics/single/scrape.yml on the server.
This One Click app uses 8428, 2003, 4242 and 8089 ports to accept metrics from different protocols. It's recommended to disable ports for protocols which are not needed. Ubuntu firewall can be used to easily disable access for specific ports.
Scraping metrics
VictoriaMetrics supports metrics scraping in the same way as Prometheus does. Check the configuration file to edit scraping targets. See more details about scraping at How to scrape Prometheus exporters.
Sending metrics
Besides scraping, VictoriaMetrics accepts write requests for various ingestion protocols. This One Click app supports the following protocols:
- Datadog, Influx (telegraph), JSON, CSV, Prometheus on port :8428
- Graphite (statsd) on port :2003 tcp/udp
- OpenTSDB on port :4242
- Influx (telegraph) on port :8089 tcp/udp
See more details and examples in official documentation.
UI
VictoriaMetrics provides a User Interface (UI) for query troubleshooting and exploration. The UI is available at http://your_server_public_ipv4:8428/vmui. It lets users explore query results via graphs and tables.
To check it, open the following in your browser http://your_server_public_ipv4:8428/vmui and then enter vm_app_uptime_seconds to the Query Field to Execute the Query.
Run the following command to query and retrieve a result from VictoriaMetrics Single with curl:
curl -sg http://your_server_public_ipv4:8428/api/v1/query_range?query=vm_app_uptime_seconds | jq
Accessing
Once the server is created, you can use Vultr's web console to start a session or SSH directly to the server as root:
ssh root@your_server_public_ipv4
