Exporter for exporting osquery ( query results to prometheus


Install osquery from

Build with go1.7

go get
go build


The exporter can be configured via configuration file and commandline parameters.

Usage of ./osquery_exporter:
  -config.file string
    	Config file (default "config.yaml")
  -log.format value
    	Set the log target and format. Example: "logger:syslog?appname=bob&local=7" or "logger:stdout?json=true" (default "logger:stderr")
  -log.level value
    	Only log messages with the given severity or above. Valid levels: [debug, info, warn, error, fatal] (default "info")
  -web.listen-address string
    	Address on which to expose metrics and web interface. (default ":9232")
  -web.telemetry-path string
    	Path under which to expose metrics. (default "/metrics")

The configuration file is mandatory, whereas the commandline parameters are optional and have resonable default values

The configuration file (YAML) defines the queries that are run via osqueryi.

  # osqueryi binary. Looked up in PATH if not specified as absolute path
  osquery: "osqueryi"
  # timeout for a single call to osqueryi
  timeout: 10s

    # a list of counter definitions
    [ - <counter definition> ... ]  
    # a list of gauge definitions
    [ - <gauge definition> ... ]  
    # a list of countervec definitions
    [ - <countervec definition> ... ]  
    # a list of gaugevec definitions
    [ - <gaugevec definition> ... ]  

There are four types of metrics, that can be exported:

counter and gauges

Counter and gauges are defined as an osquery query that returns a single line with a single element. Typical queries are select count(*) as c from <table>;. The resulting column must me named and referenced in the metric definition:

# name of the metric. Directly exported to prometheus (but prefixed with osquery_exporter_).
name: history_lines_count
# metric help
help: "number of entries in the history"
# the query to be executed via osqueryi
query: "select count(*) as count from shell_history"
# reference to the name of the result column
valueidentifier: count

It's up to the user to decide if the osquery query result is a counter or gauge. Further information about metric types and labeling recommendations can be found at

countervecs and gaugevecs

counter- and gaugevecs are analog counters and gauges, but the query result can (and should) consist of more than one result set. A single result set must contain label columns which are referenced in the metric definition:

name: users_by_shell
help: "number of users by login shell"
query:  select count(*) as count, shell from users group by shell;
valueidentifier: count
  - shell

Implicit metrics

In addition to the defined metrics defined via the configuration file, osquery_exporter implicitly creates metrics for

  • query duration (type summaryvec with a label "name")
  • query status (type gaugevec with a label "name"). A value of 0 indicates an error (including timeout), 1 indicates success.
  • number of result sets (SQL lines) per query (type gaugevec with a label "name")
