In this article, I will take you through the steps to install VictoriaMetrics on Ubuntu 20.04 LTS. According to Official Documentation, VictoriaMetrics is a cost effective, high performance open series database and scalable monitoring solution. It can be used as a long term storage for Prometheus and can also be used as drop-in replacement for Prometheus in Grafana. All the configuration done in Victoriametrics can be explicitly done through command-line flags hence making it easier for all command line lovers.

Other Important Features

  • It provides high performance and faster response.
  • It provides good horizontal and vertical scalability for both data ingestion and data querying.
  • It is optimized for time series with high churn rate.
  • It is optimized for storage with high-latency IO and low IOPS.
  • It provides global query view which means multiple Prometheus Instances can ingest data into VictoriaMetrics.
  • It provides high data compression.
  • It protects the storage from data corruption on unclean shutdown.
  • It supports metrics relabeling. More on GitHub.
  • Easy and fast backups from instant snapshots to S3 or GCS can be done with vmbackup / vmrestore tools.

victoriametrics v1.58.0+git439.c5188581 from VictoriaMetrics (f41gh7) installed

 

Step 5: Verify VictoriaMetrics

You can verify the VictoriaMetrics health by checking its /metrics page using curl http://localhost:8428/metrics query. You should see a list of internal metrics in plain text format as shown below.

root@localhost:~# curl http://localhost:8428/metrics
vm_active_force_merges 0
vm_active_merges{type="indexdb"} 0
vm_active_merges{type="storage/big"} 0
vm_active_merges{type="storage/small"} 0
vm_assisted_merges_total{type="indexdb"} 0
vm_assisted_merges_total{type="storage/small"} 0
vm_blocks{type="indexdb"} 0
vm_blocks{type="storage/big"} 0
vm_blocks{type="storage/small"} 0
vm_cache_collisions_total{type="storage/metricName"} 0
vm_cache_collisions_total{type="storage/tsid"} 0
vm_cache_entries{type="indexdb/dataBlocks"} 0
vm_cache_entries{type="indexdb/indexBlocks"} 0
vm_cache_entries{type="indexdb/tagFilters"} 2
vm_cache_entries{type="promql/parse"} 1
vm_cache_entries{type="promql/regexp"} 1
vm_cache_entries{type="promql/rollupResult"} 0
vm_cache_entries{type="storage/bigIndexBlocks"} 0

 

Step 6: Run Sample Query

You can also run a sample API query to check the usage. If you get a response with success status like below then it confirms API request/response is working as expected.

root@localhost:~# curl http://localhost:8428/api/v1/query -d 'query={job=~".*"}'
{"status":"success","data":{"resultType":"vector","result":[]}}

 

Step 7: Remove VictoriaMetrics

Once you are done with VictoriaMetrics, you can remove the snap by using snap remove victoriametrics command as shown below.

root@localhost:~# snap remove victoriametrics
victoriametrics removed
