Solutions to vmagent: command not found

How To Fix vmagent: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu vmagent is provided by victoria-metrics package.

victoria-metrics is:

VictoriaMetrics is a fast, cost-effective and scalable time-series database. It can be used as long-term remote storage for Prometheus.

Prominent features:

  • Supports Prometheus querying API, so it can be used as Prometheus drop-in replacement in Grafana. VictoriaMetrics implements MetricsQL query language, which is inspired by PromQL.
  • Supports global query view. Multiple Prometheus instances may write data into VictoriaMetrics. Later this data may be used in a single query.
  • High performance and good scalability for both inserts and selects. Outperforms InfluxDB and TimescaleDB by up to 20x.
  • Uses 10x less RAM than InfluxDB when working with millions of unique time series (aka high cardinality).
  • Optimized for time series with high churn rate. Think about prometheus-operator metrics from frequent deployments in Kubernetes.
  • High data compression, so up to 70x more data points may be crammed into limited storage comparing to TimescaleDB.
  • Optimized for storage with high-latency IO and low IOPS (HDD and network storage in AWS, Google Cloud, Microsoft Azure, etc).
  • A single-node VictoriaMetrics may substitute moderately sized clusters built with competing solutions such as Thanos, M3DB, Cortex, InfluxDB or TimescaleDB.
  • Easy operation:
    • VictoriaMetrics consists of a single small executable without external dependencies.
    • All the configuration is done via explicit command-line flags with reasonable defaults.
    • All the data is stored in a single directory pointed by -storageDataPath flag.
    • Easy and fast backups from instant snapshots to S3 or GCS with vmbackup / vmrestore.
    • Data migration between VictoriaMetrics, Prometheus and InfluxDB with vmctl.
  • Storage is protectedfrom corruption on unclean shutdown (i.e. OOM, hardware reset or kill -9) thanks to the storage architecture.
  • Supports metrics’ scraping, ingestion and backfilling (#backfilling) via the following protocols:
    • Metrics from Prometheus exporters such as node_exporter.
    • Prometheus remote write API
    • InfluxDB line protocol
    • Graphite plaintext protocol with tags if -graphiteListenAddr is set.
    • OpenTSDB put message if -opentsdbListenAddr is set.
    • HTTP OpenTSDB /api/put requests if -opentsdbHTTPListenAddr is set.
    • /api/v1/import.
  • Ideally works with big amounts of time series data from Kubernetes, IoT sensors, connected cars, industrial telemetry, financial data and various Enterprise workloads.
  • Has open source cluster version.

To fix this problem, we can install more using the command below.

sudo apt-get -y install victoria-metrics

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install victoria-metrics.

sudo apt -y install victoria-metrics

Or if you have aptitude installed you can use the following command.

sudo aptitude install victoria-metrics
