The query command line tool is meant to be a quick debugging tool for extracting data from OpenTSDB. The HTTP API will usually be much quicker when querying data as it incorprates caches and open connections to storage. Results are printed to stdout in a text format with one data point per line.

Note that a query may return data points before and after the timespan requested. These are used in downsampling and graphing.


query [Gnuplot opts] START-DATE [END-DATE] <aggregator> [rate] [counter,max,reset] [downsample N FUNC] <metric> [<tagk=tagv>] [...<tagk=tagv>] [...queries]
Name Data Type Description Default Example
Gnuplot opts Strings Optional values used to generate Gnuplot scripts and graphs. Note that the actual graph PNG will not be generated, only the files (written to the temp directory) +wxh=1286x836
START-DATE String or Integer Starting time for the query. This may be an absolute or relative time. See Dates and Times for details 1h-ago
END-DATE String or Integer Optional end time for the query. If not provided, the current time is used. This may be an absolute or relative time. See Dates and Times for details Current timestamp 2014/01/01-00:00:00
aggregator String A function to use when multiple timeseries are included in the results sum
rate String The literal rate if the timeseries represents a counter and the results should be returned as delta per second rate
counter String Optional literal counter that indicates the underlying data is a monotonically increasong counter that may roll over counter
max Integer A positive integer representing the maximum value for the counter Java Long.MaxValue 65535
resetValue Integer An optional value that, when exceeded, will cause the aggregator to return a 0 instead of the calculated rate. Useful when data sources are frequently reset to avoid spurious spikes. 65000
downsample N FUNC String Optional downsampling specifier to group data into larger time spans and reduce the amount of data returned. Format is the literal downsample followed by a timespan in milliseconds and an aggregation function name downsample 300000 avg
metric String Required name of a metric to query for sys.cpu.user
tagk=tagv String Optional pairs of tag names and tag values host=web01
additional queries String Optional additional queries to execute. Each query must follow the same format starting with an aggregator. All queries share the same start and end times. sum tsd.hbase.rpcs type=scan

For more details on querying, please see Querying or Reading Data.

Output Format

Data is printed to stdout with one data point per line. If one or more Gnuplot options were specified, then scripts and data files for each query will be written to the configured temporary directory.

<metric> <timestamp> <value> {<tagk=tagv>[,..<tagkN=tagvN>]}


  • metric Is the name of the metric queried
  • timestamp Is the absolute timestamp of the data point in seconds or milliseconds
  • value Is the data point value
  • tagk=tagv Is a list of common tag name and value pairs for all timeseries represented in the query
