graylogger is a python script born out of necessity. Use graylogger.py to send GELF-formatted messages to a graylog host. You may log string messages, file contents or read from stdin, add additional fields. Host name and timestamp will be provided automatically.
The help option -h displays the usage page:
./graylogger.py -h
usage: graylogger.py [options] SERVER MESSAGE
send a message to a graylog server
positional arguments:
server graylog server name
message message being sent or @FILENAME to read from FILENAME
or - to read from StdIn
optional arguments:
-h, --help show this help message and exit
-l {DEBUG,INFO,WARNING,CRITICAL,ERROR}, --level {DEBUG,INFO,WARNING,CRITICAL,ERROR}
log level (defaults to ALERT)
-f FACILITY, --facility FACILITY
facility name (defaults to 'PythonLogger')
-p PORT, --port PORT graylog port (defaults to 12201)
-d DATA, --data DATA additional data field (key:value)
-t TEMPLATE, --template TEMPLATE specify log message template
-n, --nolog do not log, simulate and show on console
Use the -d (or --data) option to supply additional fields to graylogger. The value consists of the field name and the field value, separated by a comma. If the field name or value contain white space, make sure to quote the fiel data (e.g. -d "Merchant:ACME Inc."). Separator is the first comma, so it is perfectly to valid to have a comma in the field value string. You may provide an arbitrary number of -d options as shown below:
./graylogger.py -l DEBUG -f "ETL" graylog.company.example.com "Start pricing ETL job" -d "Merchant:ACME Inc." -d Database:pricing_prod
The message parameter is a string. If you have whitespace in the string, be sure to enclose it in quotes:
./graylogger.py -l DEBUG -f "ETL" graylog.company.example.com "Processing startet at `date +%s`"
Using a single dash character - as the message, graylogger will read from standard input:
output_generating_program | ./graylogger.py -l INFO -f "ETL" graylog.company.example.com -
If the first character of the message parameter is a @, the message will be read from the file name directly following the @, e.g. @result.txt. If needed, a path may be specified (e.g. @/tmp/some/file.log):
./graylogger.py -l WARNING -f "ETL" graylog.company.example.com @warnings.txt
