Command Reference

This page describes commands for interacting with EventStore

DANA Plugin

ESQuery

ESQuery.py provides a command line interface to get information from the EventStore DB. It can currently be found in $EVENTSTORE_BASE/src/EventStoreToolkit .

To use ESQuery.py, you need to set up the EventStore Tools as described here. Please also configure a ~/.esdb.conf file containing the following contents: [note]

eventstore:eventstoreisgreat

More information on this file can be found here.

Please make sure that you've selected the correct main database, either by setting the ESDB environment variable, or by using the -db option.

This program supports many different queries, as shown below. For example, to get a list of runs contained in the "recon" grade (i.e. REST data), use the following command: <syntaxhighlight> ./ESQuery.py -db [email protected] runs recon </syntaxhighlight>

There is also command-line help options as shown here:

ifarm1401> ./ESQuery.py 

Usage: ESQuery [ -help ] [ --help ] [ -examples ] [ -profile ]
               [ -verbose ] [ -historyfile <filename> ]
               [ -db <name@host:port:socket or fileName> ]
               [ -user <username> -password <password> ] ]
               [ -logFile </path/filename>or 'stdout' or 'stderr'> ]
               [ -noHeader ]

Use ESDB environment variable to setup your DB
     Example: ESDB=EventStoreTMP@hallddb
     Example: ESDB=/tmp/sqlite.db
User name and password for MySQL access can be stored into $HOME/.esdb.conf as
<username>:<password>

Options can be specified in any order.
For option description please run 'ESQuery --help'
For use cases please run 'ESQuery -examples'

Historical

For reference, this is what things were like at CLEO:

 Description: eventstore

   Access the eventstore database 

 eventstore in <YYYYMMDD> [<grade> [<skim>]] [runs <low> [<high>]] 
                           [<run info query>]
                           [dbDir <dir>] [streams <stm> [<stm>] ] 
                       reads requested data from the event store
 where 
    <YYYYMMDD>         date of the version of the <grade> to use
    <grade>            'grade' of the data to use (default is physics)
    <skim>             the event skim within the grade to use
                       (default is all)
    runs <low> <high>  restricts runs to be between <low> and <high>
                       if only <low> given, only runs over that run
                       (default is to run over all runs)
    <run info query>   allows you to choose runs based on their properties
                       do 'eventstore query_help' for details
    dbDir <dir>        select the directory holding the database
                       (default is to use value for $C3_EVENTSTORE)
    streams <strm>     list of streams to read from event store
                       (default is to read all available)

 eventstore info [dbDir <dir>] < request >
        see 'eventstore info help' for details 

 eventstore query_help 
                       explains what run info queries are available

 %% SYSTEM-EventStoreModuleBase.EventStoreCommandBase: 

eventstore info [ dbDir <dir> ] < request >

where request may be 
  runs <datestamp> [<grade> [<skim>] ] [runs <min> [<max>]] 
    [<run info query>]    prints available runs in DB
                          that match criteria 

  grades                  prints available grades in DB

  skims <datestamp> <grade> 
                          print skims available for the grade

  actualDate <datestamp> <grade> 
                          print actual internal date used

  versions   <datestamp> <grade> [-verbose]
                          print run ranges versus versions
                          use -verbose option for more details

  dbContent <dbName>      prints content of DB:

you need to provide dbName from the following list:
all, FileID, KeyFile, Location, RunUID, Version, SpecificVersion, GraphPath, , PathDepend, FileType, OrphanFile
