Monitor HTTP access logs in your terminal.
Build
$ go get github.com/tools/godep
$ godep go test
$ godep go build
Run
$ ./http_log_console -h
Usage of ./http_log_console:
-f string
HTTP log file to monitor
-i int
Interval at which statistics should be emitted (default 10)
-t int
Alarm threshold (default 100)
-w int
Alarm evaluation period (default 120)
$ ./http_log_console -f /var/log/nginx/access.log -i 10 -t 1000 -w 120
To-Do
- The log processor relies on a fixed regexp pattern for parsing the logs. For greater flexibility, it should be split into 2 components: one for tailing the log file and another one for parsing the payload.
- The log processor should expose metrics about how many logs have been processed, broken down by success/failure.
- The pipeline is assembled "manually" in the main() function. We should implement a generic pipeline system that would allow an arbitrary number of workers consuming the same input stream (a typical example would be to run multiple alarm workers) and even chaining workers one after the other.
- The statistic and alarm workers return respectively slices of strings and strings. Instead they should return structures implementing the String() interface.
- The implementation of the alarm testing is quite crude and should be revised to be more deterministic (eg not rely on arbitrary timeouts).
