This ensures that elasticsearch doesn't parse it as an object. There are
too many combination of job opts so we don't want elasticsearch to be
parsing and indexing this field as an object.
This commit improves the logging of Sidekiq errors when
`ENABLE_LOGSTASH_LOGGER` is set to 1. Prior to this change, we would
only log the message and the backtrace. After this change, useful
information like `job.class`, `job.opts`, `job.problem_db`,
`exception.class` and `exception.message` are included in the log line
as well.
This commit updates `DiscourseLogstashLogger#add_with_opts` to avoid
logging messages that matches regexp patterns configured in
`Logster.store.ignore`. Those error logs are mostly triggered by clients
and do not serve any useful purpose.
This commit updates `DiscourseLogstashlogger` to add the
`exception_class` and `exception_message` field to the log line when the
`progname` of the log message is `web-exception` which is Logster's
logging of exceptions during a web request.
The `exception_class` and `exception_message` fields allows consumers of
the logs to easily group logs together.
In our official Docker image, running git commands results in the
following error:
```
fatal: detected dubious ownership in repository at '/var/www/discourse'
To add an exception for this directory, call:
git config --global --add safe.directory /var/www/discourse
```
This commit rewrites `DiscourseLogstashLogger` to not be an instance
of `LogstashLogger`. The reason we don't want it to be an instance of
`LogstashLogger` is because we want the new logger to be chained to
Logster's logger which can then pass down useful information like the
request's env and error backtraces which Logster has already gathered.
Note that this commit does not bother to maintain backwards
compatibility and drops the `LOGSTASH_URI` and `UNICORN_LOGSTASH_URI`
ENV variables which were previously used to configure the destination in
which `logstash-logger` would send the logs to. Instead, we introduce
the `ENABLE_LOGSTASH_LOGGER` ENV variable to replace both ENV and remove
the need for the log paths to be specified. Note that the previous
feature was considered experimental as stated in d888d3c54c
and the new feature should be considered experimental as well. The code
may be moved into a plugin in the future.
