heka-symfony2-monolog-decoder

A heka decode written in lua for parsing symfony2 formatted monolog messages

installation

You can place the lua decoders anywhere as long as heka can read them.

usage

There are two decoders available. One for decoding log messages in your app/logs directory and another one that decodes monolog messages that were logged to syslog (useful if you configured your Symfony 2 application to log to syslog).

usage: monolog decoder

To use the plain Symfony2 Monolog Decoder put the following in your /etc/hekad.toml:

$ cat /etc/hekad.toml
[Symfony2MonologFileInput]
type = "LogstreamerInput"
log_directory = "/var/www/app/logs"
file_match = 'prod\.log'
decoder = "Symfony2MonologDecoder"

[Symfony2MonologDecoder]
type = "SandboxDecoder"
filename = "/etc/symfony2_decoder.lua"

Adjust log_directory and filename according to your setup.

usage: syslog monolog decoder

To use the Syslog Symfony2 Monolog Decoder you need to configure your symfony2 application to log to syslog by changing config_prod.yml:

$ cat app/config/config_prod.yml
# ...
monolog:
    handlers:
        main:
            type: syslog
            ident: myapplication
# ...

And configure rsyslog to send all logs with application name myapplication to a seperate file:

$ cat /etc/rsyslog.d/90-myapplication.conf
if $programname == 'myapplication' then /var/log/myapi.log

Where programname and ident are the same string.

Now you can configure heka to watch this file:

$ cat /etc/hekad.toml
[SyslogSymfony2MonologFileInput]
type = "LogstreamerInput"
log_directory = "/var/log"
file_match = 'bmpapi\.log'
decoder = "SyslogSymfony2MonologDecoder"

[SyslogSymfony2MonologDecoder]
type = "SandboxDecoder"
filename = "/etc/syslog_symfony2_decoder.lua"

[SyslogSymfony2MonologDecoder.config]
type = "RSYSLOG_TraditionalForwardFormat"
template = '%TIMESTAMP% %HOSTNAME% %syslogtag:1:32%%msg:::sp-if-no-1st-sp%%msg%'
tz = "Europe/Amsterdam"

For debugging purposes you can use the build-in RstEncoder to see how the fields get serialized:

$ cat /etc/hekad.toml
# ...
[RstEncoder]

[LogOutput]
message_matcher = "TRUE"
encoder = "RstEncoder"
# ...
