Allows analysis of arangodbs agency logs.

Install required python dependencies.

pip install -r requirements.txt

Given a JSON encoded agency log in a file, start with

python aaa.py <log file> <snapshot file>
python aaa.py [-k] http|https://<endpoint> <jwt>
python aaa.py [-k] -u http|https://<endpoint> username:password

Close the program via :q. Use -k to disable ssl certificate validation.

On the left side you can see a list of all log entries ordered by time. Use the UP/DOWN to navigate. The right side contains different views of information. Currently supported modes are

• log: display the selected log entry
• store: display the state of the agency at the selected moment (reconstructed from log entries)

In both modes one can scroll the text using UP/DOWN keys. Focus can be switched using TAB. To change the view mode either use F1/F2 or :view <mode>.

When in store mode with focus on the view side, use p to modify the displayed path of the agency. Use TAB to auto complete your input.

When in the left hand side, use f to enter a regular expression to filter entries by requested paths. Use g to do a basic grep like search on the log entries. Reset filters via R.

To dump the content of the JSON view into a file use :dump filename.

In the log list you can toggle entry markers using m. To delete the marking immediately use M.

You can save and restore states of the analyizer. To store a state use: :(s|save|store) [name] where name is the name of the state. if empty a prompt will open.

To restore a state use: :(r|restore) [name] again name is optional and if empty a prompt with autocomplete will open.

You can use 0-9 keys as shortcuts to restore state "0"-"9". To save the state use ALT + "x".

You can make aaa wait for a cluster to become available, then start following the agency live. This is particularly useful during integration tests.
Before starting a test suite, run:
python aaa.py --follow --live $(python wait-for-agency.py)

You can modify the annotations format. There are currently three topics:

• server
• collection
• shard

The format string is a Python Format string. Each topic provides a specific set of format keys as described below. Format strings look like this:

Collection `{database}/{name}`

You can change a format string using :f <topic>.

All key from the Supervision/Health entry of that server are available.

All keys in the collection entry are available. Additionally database is available.

Same as for collection but additionally shardId and servers.
