ax events dump

Dumping events from a node

USAGE:
    ax events dump [FLAGS] [OPTIONS] <QUERY> <NODE>

FLAGS:
    -h, --help       Prints help information
    -j, --json       Format output as JSON
    -q, --quiet      suppress progress information on stderr
    -V, --version    Prints version information
    -v               Verbosity level. Add more v for higher verbosity (-v, -vv, -vvv, etc.)

OPTIONS:
        --cloud <TOKEN>      send dump via the cloud (start restore first to get the token)
    -i, --identity <FILE>    File from which the identity (private key) for authentication is read
    -o, --output <FILE>      file to write the dump to

ARGS:
    <QUERY>    selection of event data to include in the dump
    <NODE>     the IP address or <host>:<admin port> of the node to perform the operation on

An event dump is a compressed file that contains information on the source Actyx node and a selection of events. The events are selected using the AQL query given as an argument, you can filter in any way you like. The purpose of an event dump is to take the selected event history from a production environment and bring it into testing or development, so that application logic can be examined (e.g. to identify bugs).

Exporting all events for a given app

$ ax events dump -o out 'FROM appId(com.example.my-app)' localhost
connected to localhost [127.0.0.1:4458]
info block written
892 events written (maximum size was 4303)

The out file can now be copied to a development machine and examined using ax events restore. You can also write the dump to standard output (by leaving out the -o option) or send it via the cloud — see restoring via the cloud.
