Vespa Command-line Tools

This is the reference for the Vespa command-line tools.


vespa-configproxy-cmd is a status and control tool for the config proxy. The config proxy runs on all nodes as a proxy for one or more config servers. It connects to the config proxy on localhost by default.

Synopsis: vespa-configproxy-cmd -m method [args]


$ vespa-configproxy-cmd -m sources
-m method, available methods are:
cache Output the config proxy cache content (overview)
getConfig Get config (see vespa-get-config)
getmode Outputs the current mode of the config proxy
setmode Use default or memorycache - example
invalidatecache Clears the current cache in config proxy
cachefull Output the config proxy cache content (including config payload)
sources Output the config proxy's upstream config sources
updatesources Updates the config proxy's upstream config sources to the supplied ones

-s hostname, optional
-h help text and usage


vespa-configserver-remove-state removes config server state on the host.

Synopsis: vespa-configserver-remove-state [-force]


-force Do not ask for confirmation before removal


vespa-config-status can run on any machine in a Vespa cluster and outputs a list of all running services which is running with an outdated application package. It can be invoked without any arguments, or with optional arguments.

Synopsis: vespa-config-status [-v] [-c host] [-c host:port] [-f host0,...,hostN]


$ vespa-config-status


-v Verbose - show all services, even if they are up to date
-c arg Get Vespa cluster configuration from the config server specified by host and port. Use host or host:port for config server
-f Filter to only query config status for the given comma-separated set of hosts


vespa-deploy deploys an application package, using the deploy API. Refer to the deploy reference for details.

Synopsis: vespa-deploy [-h] [-v] [-n] [-f] [-t timeout] [-c hostname] [-p port] prepare|activate|upload|fetch|help [args]


$ vespa-deploy prepare [application-path|zip-file] && vespa-deploy activate
$ vespa-deploy prepare && vespa-deploy activate
prepare vespa-deploy prepare combines the upload and prepare steps.
activate vespa-deploy activate invokes the activate step.
upload vespa-deploy upload uploads an application package
fetch vespa-deploy fetch fetches an application package. Useful to get the active configuration for an instance.
help Same as -h

-h Show help text
-v Verbose
-n Dry-run deployment
-f Force - ignore validation errors
-t Timeout
-c Config server hostname
-p Config server port


vespa-destination is a simple receiver for messagebus messages. It outputs messages received on stdout. Also see vespa-visit-target.

Synopsis: vespa-destination [options]


$ vespa-destination --name msg_sink


--instant Reply in message thread
--name arg Slobrok name to register
--maxqueuetime arg Adjust the in queue size to have a maximum queue wait period of this many ms (default -1 = unlimited)
--silent #nummsg Do not dump anything, but progress every #nummsg
--sleeptime arg The number of milliseconds to sleep per message, to simulate processing time
--threads arg The number of threads to process the incoming data
--verbose Dump the contents of certain messages to stdout


vespa-feeder is a feeding client that parses JSON input as Vespa document operations and sends to a Vespa application. It parses the content of the input sequentially, and feeds each operation in order. However, since many operations will be pending at any time, and because the processing time of an operation varies, there is no guarantee as to which order operations reach the content nodes. As this can be important when it comes to operations that apply to the same document id, there is logic in place to not send an operation for a document id to which there is already a pending operation.

vespa-feeder prints a report at end of feed. To print this report once a minute, use --verbose:

Messages sent to vespa (route default) :
PutDocument: ok: 999997 msgs/sec: 411.38 failed: 0 ignored: 0 latency(min, max, avg): 2, 4360, 99
ignored reports the number of documents that could not be routed to any content clusters because they did not match any of the configured document types or selections - examples are:
  • A document type is removed from the application and the feed file contains documents with this type
  • One or more selection expressions restrict the documents the cluster accepts, and the feed file contains documents that are excluded. An example is feeding expired documents - a selection for documents that are less than 30 days old and the feed file contains documents that are 30+ days old

Synopsis: vespa-feeder [--abortondataerror true|false] [--abortonsenderror true|false] [--file arg] [--maxpending arg] [--maxpendingsize arg] [--maxfeedrate arg] [mode standard|benchmark] [--noretry] [--retrydelay arg] [--route arg] [--timeout arg] [--trace arg] [--validate] [--dumpDocuments filename] [priority arg] [--numthreads arg] [create-if-non-existent] [-v,--verbose] filename


$ vespa-feeder file.json

vespa-get-config is a command line tool to get configuration from a config server or config proxy. By default it connects to the config proxy on localhost, fetches config from its cache and prints the config payload on stdout. Configuration is addressed using name and configId. If configId is omitted, the global and default data for that name is returned. The default port number is 19090, the config proxy's port - use 19070 to access a config server. Also check ports.

Synopsis: vespa-get-config -n defName -i configId <option> [args]


$ vespa-get-config -n container.statistics -i search/


-n config definition name, including namespace (on the form <namespace>.<name>)
-i config id, optional

-w timeout, default value 10, optional
-s server hostname, default localhost, optional
-p port, default 19090, optional
-d debug mode, optional
-h help text and usage


Use vespa-index-inspect to inspect indexed data - useful when troubleshooting query rewriting. It shows posting list information (per token or all/range), or dumps the indexed tokens:

vespa-index-inspect showpostings [--indexdir indexDir] --field field word

vespa-index-inspect showpostings [--indexdir indexDir] [--field field] --transpose \
  [--docidlimit docIdLimit] [--mindocid mindocid]

vespa-index-inspect dumpwords [--indexdir indexDir] --field field \
  [--minnumdocs minnumdocs] [--verbose] [--wordnum]
Synopsis:vespa-index-inspect showpostings|dumpwords [--indexdir path] [--field fieldname] [--transpose] [--minnumdocs count] [--docidlimit docIdLimit] [--mindocid mindocid] [--verbose] [--wordnum] [word]

Example (make sure to flush the index before using):

$ vespa-proton-cmd --local triggerFlush && \
  vespa-index-inspect dumpwords \
  --indexdir /opt/vespa/var/db/vespa/search/ \
  --field title
bad	2
so	1
--indexdir path Index location
--field fieldname Field to analyze
--transpose Dump all tokens
--minnumdocs count Minimum number of documents to analyze
--docidlimit docid Dump up to this doc id
--mindocid docid Start from this docid
--wordnum Also dump token numbers
--verbose Verbose output


Print or modify log levels for a VESPA service, stored in $VESPA_HOME/var/db/vespa/logcontrol/service.logcontrol. Refer to controlling log levels for details. component-specification specifies which sub-components of the service should be controlled. If empty, all components are controlled:

  • x. : Matches only component x
  • x : Matches component x and all its sub-components
Synopsis (show log levels): vespa-logctl [OPTION] <service>[:component-specification]

Synopsis (set log levels): vespa-logctl [OPTION] <service>[:component-specification] <level-mods>

level-mods are defined as : <level>=<on|off>[,<level>=<on|off>]...

level is one of: all, fatal, error, warning, info, event, config, debug, spam

Example: For service qrserver, set and all sub-components of to enable all except spam and debug:

$ vespa-logctl all=on,spam=off,debug=off
-c Create the control file if it does not exist (implies -n)
-a Update all .logcontrol files
-r Reset to default levels
-n Create the component entry if it does not exist
-f file Use <file> as the log control file
-d dir Look in <dir> for log control files


vespa-logfmt reads Vespa log files, selects messages, and writes a formatted version of these messages to standard output. If no file argument is given, vespa-logfmt will read the last Vespa log file $VESPA_HOME/logs/vespa/vespa.log (this also works with the -f option). Otherwise, reads only the files given as arguments. To read standard input, supply a single dash ’-’ as a file argument. Refer to the logs reference.

Synopsis: vespa-logfmt [-l levellist ] [-s fieldlist ] [-p pid ] [-S service ] [-H host ] [-c regex ] [-m regex ] [-f ] [-N ] [-t ] [-ts ] [file …]


Display only messages with log level "event", printing a human-readable time (without any fractional seconds), the service generating the event and the event message:

$ vespa-logfmt -l event -s fmttime,service,message
[2017-09-05 06:16:16] config-sentinel  stopped/1 name="sbin/vespa-config-sentinel -c hosts/vespa-container (pid 1558)" pid=1558 exitcode=1

[2017-09-05 06:17:00] configserver     count/1 name=configserver.requests value=0
Display messages with log levels that are not any of info, debug, or event, printing the time in seconds and microseconds, the log level, the component name, and the message text:
$ vespa-logfmt -l all-info,-debug -s level -s time,usecs,component,message -t -l -event
1504592294.738000 WARNING : No config found for name=sentinel,namespace=cloud.config,configId=hosts/vespa-container within timeout, will retry
1504592296.388000 WARNING : Request callback failed: APPLICATION_NOT_LOADED. Connection spec: tcp/localhost:19070, error message: Failed request (No application exists) from Connection { Socket[addr=/,port=37806,localport=19070] }
1504592307.949461 WARNING : config-sentinel Connection to tcp/localhost:19090 failed or timed out
1504592307.949587 WARNING : config-sentinel FRT Connection tcp/localhost:19090 suspended until 2017-09-05 06:19:07 GMT
-l levellist (--level=levellist) Filter messages by log level. By default only messages of level fatal, error, warning, and info will be included, while messages of level config, event, debug, and spam will be ignored. This option allows you to replace or modify the list of log levels to be included. levellist is a comma separated list of level names.
  • The name all may be used to add all known levels
  • You may use + or - in front of terms to add or remove from the current (or default) list of levels instead of replacing it
  • Adding term
-s fieldlist Select which fields of log messages to show. The output field order is fixed. When using this option, only the named fields will be printed. The default fields are as [-s fmttime,msecs,level,service,component,message]. The fieldlist is a comma separated list of field names. The name all may be used to add all possible fields. Prepending a minus sign will turn off display of the named field. Starting the list with a plus sign will add and remove fields from the current (or default) list of fields instead of replacing it. Using this option several times works as if the given fieldlist arguments had been concatenated into one comma-separated list. Fields:
time Print the time in seconds since the epoch. Ignored if fmttime is shown
fmttime Print the time in human-readable [YYYY-MM-DD HH:mm:ss] format. Note that the time is printed in the local timezone; to get GMT output, use env TZ=GMT vespa-logfmt
msecs Add milliseconds after the seconds in time and fmttime output. Ignored if usecs is in effect
usecs Add microseconds after the seconds in time and fmttime output
host Print the hostname field
level Print the level field (uppercased)
pid Print the pid field
service Print the service field
component Print the component field
message Print the message text field. You probably always want to add this
-p pid Select messages where the pid field matches the pid string
-S service Select messages where the service field matches the service string
-H host Select messages where the hostname field matches the host string
-c regex Select messages where the component field matches the regex, using perlre regular expression matching
-m regex Select messages where the message text field matches the regex, using perlre regular expression matching
-f Invoke tail -F to follow input file
-N Dequote quoted newlines in the message text field to an actual newline plus tab
-t Format the component field (if shown) as a fixed-width string, truncating if necessary
-ts Format the service field (if shown) as a fixed-width string, truncating if necessary

vespa-remove-index is a command line tool to remove index data on a Vespa search node, by wiping out selected files and subdirectories found in $VESPA_HOME/var/db/vespa/. This process is irreversible and the indexes deleted can not be recovered.

Stop services before running it - example:

$ vespa-stop-services && vespa-remove-index -force && vespa-start-services    

Synopsis:vespa-remove-index [-force] [-cluster name]


$ vespa-remove-index
[info] For cluster music distribution key 0 you have:

vespa-stat is a tool to fetch statistics about a specific user, group, bucket, gid or document. vespa-stat works in two stages. The first stage is to figure out the actual buckets we want to look at. In the second stage, it can dump the located buckets. For each command line option, only the relevant documents will be dumped (the document for --document/--gid, or the user/group's documents for --user/--group). This stage can be turned on by adding --dump, but is default on for the case of --document/--gid.

Synopsis: vespa-stat [options]


$ vespa-stat --document id:my_namespace:my_search::12345678-4fb7-3797-ae9a-d4d7a4e6e085
