# logan

Log analyzer for log4j logs.

### Help

* `-D` : date filtering

* `-T` : time filtering

* `-S` : severity filtering

* `-M` : error messaga filtering

### Good to know:

* `-M` has to be the last option, it can contain white spaces

* The order and the multiplicity of `-D`, `-T`, `-S` are irrelevant.

    The last one will be chosen.

### Usage:

* `logan.sh -D2012-12-08` : it seeks all loglines with this match in date column

* `logan.sh -D2012-12-* -SSEVERE` : it seeks all lines in all days in `Dec.2012.` with `SEVERE` level

* `logan.sh -D2012-12-* -D2012-12-08` : it takes all lines matching on `08.Dec.2012`

* `logan.sh -T12:*:* -D2012-12-*` : it takes all lines matching on `Dec.2012` between noon and 1PM

* `logan.sh -MError message comes here` : it seeks all lines matching on `"Error message comes here"`

* `logan.sh -MError msg -D2012-12-12` : it seeks `"Error msg -D2012-12-12"`
