Logging Design (Refactor)
|
||||
-------------------------
|
||||
|
||||
Logging is how the server communicates to developers and administrators about the state
|
||||
of the service, and how operations are performing and what they are doing. It's important
|
||||
this is clear in how it communicates. Today (2020-05-12) the log has been written with
|
||||
development in mind, and has a structure that has as a result, become hard to parse and
|
||||
understand. This has motivated a rewrite of logging to improve how the servers state
|
||||
and errors are communicated to users.
|
||||
|
||||
Use Cases
|
||||
---------
|
||||
|
||||
* Developer Bug Reports
|
||||
|
||||
A developer should be able to see the internal state of the server, and why any decision
|
||||
or logic path was taken, so that errors or logic can be analysed post-incident. The
|
||||
information in the log and the source code should be enough to resolve any issues, as we
|
||||
may not have LLDB access to any consumers site, or any effective reproducer.
|
||||
|
||||
* Security Audits
|
||||
|
||||
We must be able to see why any security decision was made, such as credential validation,
|
||||
access control application, or group/claim issuing to a session. This should be connected
|
||||
to the IP and other identifiers of the caller.
|
||||
|
||||
* Error Analysis
|
||||
|
||||
For an administrator, they must be able to determine why an operation is failing in detail
|
||||
so they can advise on how a consumer or user could change their behaviour to improve the
|
||||
situation (beyond the error messages we return).
|
||||
|
||||
* Performance
|
||||
|
||||
Administrators and Developers should be able to analyse fine grained information about the
|
||||
performance of any operation, and make informed decisions about tuning (such as caches or
|
||||
or threads), and developers should be able to identify code paths that are under pressure
|
||||
and could be targets for improvement.
|
||||
|
||||
* Containers/Systemd
|
||||
|
||||
Logs should be emitted on stdout/stderr as this is the easiest interface for existing
|
||||
log aggregation systems to collect data from.
|
||||
|
||||
Details
|
||||
-------
|
||||
|
||||
As developers we should indicate what messages are relevant to what use case as part of the
|
||||
message. Log levels are used in other services, but that allows messages to be missed. Instead
|
||||
we log every "service" always, but filter them to different locations.
|
||||
|
||||
This leads to the following log categories:
|
||||
|
||||
* Analysis
|
||||
* Display of all logic branches and why decision points or paths taken
|
||||
* A unique event ID that associates related log messages
|
||||
* Performance
|
||||
* Cache and DB metrics available
|
||||
* Performance frames of timing of key points
|
||||
* Structure of the performance frames to understand the execution paths taken.
|
||||
* Display of query optimisation
|
||||
* Display of query planning and application
|
||||
* Failure (server failure)
|
||||
* Hard Errors
|
||||
* Warning (admin should take action)
|
||||
* Possible misconfiguration
|
||||
* OperationError (user mistake, op mistake etc)
|
||||
* All error reports and finalised result summaries logged
|
||||
* The unique event ID is provided in any operation success or failure.
|
||||
* Security (aka audit)
|
||||
* Filtering of security sensitive attributes (via debug/display features)
|
||||
* Display of sufficent information to establish a security picture of connected actions via the user's uuid/session id.
|
||||
* Tracking of who-changed-what-when-why
|
||||
* Replication
|
||||
* TODO
|
||||
|
||||
It can be seen pretty quickly that multiple message types are useful across categories. For
|
||||
example, the unique event id for all messages, how hard errors affect operation errors
|
||||
or how an operation error can come from a security denial.
|
||||
|
||||
Logging must also remain a seperate thread and async for performance.
|
||||
|
||||
This means that the best way to declare these logs is a unified log which can be filtered based
|
||||
on the admins or consumers needs.
|
||||
|
||||
API
|
||||
---
|
||||
|
||||
For all types, it's important that we can associate all related events correctly. When the
|
||||
operation initiates we assign an event-id that is part of the audit trail.
|
||||
|
||||
Statistics
|
||||
==========
|
||||
|
||||
Stats should be accumulated in a statistics variable so that we can determine possible
|
||||
tuning and other events related. Useful stats would be:
|
||||
|
||||
* Cache Hits
|
||||
* Cache Misses
|
||||
* Cache Inclusions
|
||||
|
||||
* Number of Searches
|
||||
* Number of Entries Modified
|
||||
|
||||
This would be then logged as a structured line such as:
|
||||
|
||||
{ 'entry_cache_miss': 8, 'idl_cache_miss': 8, 'entry_cache_hit': 16', .... }
|
||||
|
||||
This would also then be fed back to the global stats thread for averaging.
|
||||
|
||||
Performance
|
||||
===========
|
||||
|
||||
The key metric for performance is time-in-function so it would be good to be able to
|
||||
build a value like:
|
||||
|
||||
{
|
||||
'name': 'do_search',
|
||||
'time': x,
|
||||
'pct': 100,
|
||||
called: [
|
||||
{
|
||||
'name': 'filter2idl',
|
||||
'time': x',
|
||||
called: [],
|
||||
},
|
||||
{
|
||||
...
|
||||
}
|
||||
]
|
||||
}
|
||||
|
||||
This would allow a rich view of how much time went to any function at a high level, as then
|
||||
further investigation can occur.
|
||||
|
||||
Query Analysis
|
||||
==============
|
||||
|
||||
To analyse a query we need:
|
||||
|
||||
* The original query
|
||||
* The optimised version, with index tagging/profiling choices.
|
||||
* The idl's that were loaded and how the query was applied
|
||||
* The idl of the final result set.
|
||||
|
||||
Security Events
|
||||
===============
|
||||
|
||||
* What access controls were considered?
|
||||
* Who authenticated and where from?
|
||||
* Audit of who modified what when why.
|
||||
|
||||
Analysis
|
||||
========
|
||||
|
||||
This is generally what is "debug" logging, which is just decision points and verbose
|
||||
descriptions of what we went where.
|
||||
|
||||
Admin Notification
|
||||
==================
|
||||
|
||||
This is warnings or errors that the admin should be aware of.
|
||||
|
||||
User Events
|
||||
===========
|
||||
|
||||
This must associate what happened for a user
