Informations about the package log-monitor
log-monitor
An active log monitor based on the tail
command.
Why use log-monitor?
Sometimes we want to know what is happening when crontab task is running or what errors had been written into the php error log by php script, and we want to know quickly. log-monitor can help you to monitor the log and notify the users who want to know.
What can log-monitor do?
- monitor the log by the tail command
- notify users when there is an error
- custom log filter interface, which will check the log is error or not
- custom notification interface, which will notify the users
- custom reader interface, if you do not want to use the tail command
How to use log-monitor?
talk is cheap, show you the code:
There are three interfaces:AbstractReader
, NotificationInterface
, FilterInterface
.
If you want to read log for somewhere else, you can create a class which extends AbstractReader
.
If you want to filter your log in different way, you can create a class which implements FilterInterface
.
If you want to send message to somewhere else, you can create a class which implements NotificationInterface
.
How it works?
When you have created a MonitorTask object and call the run
method,
it will start a sub process and call the tail
command in the sub process. Then it will
read from the pipe and check the log by filter that if it is error or not. If there is an
error, it will call the notification to notify the users who want to know.
Just do not forget to call wait
method to wait the sub process.
If you have many logs to monitor, you can use the Monitor to manage them. show you the code:
Just remember that when you call the start
method, do not forget to call wait
method.
