Mixtail watches multiple log files( or command output) and output them in single console. This command is useful for watching file(or command output) across many servers.
At first, create a config file(YAML) like following. Config file creation is also available by running "mixtail -example".
input:
xxx-log:
type: ssh
host:
- 192.168.1.10
- 192.168.1.11
- 192.168.1.12
- 192.168.1.13
- 192.168.1.14
- 192.168.1.15
# if you don't want define user,pass or identity here,
# you can define them in external file, see "Advanced usage" section.
user: user_name
pass: password
# identity: /path/to/key
command: tail -f /tmp/test.log
yyy-log:
type: ssh
host: 192.168.1.10
user: user_name
pass: password
# identity: /path/to/key
command: tail -f /tmp/another.log | grep "error"
Then, running mixtail command with config file name.
mixtail config.yml
The command starts wathcing according to config file, and output all output into a single console.
e.g.
[192.168.1.10: xxx-log] XX.XX.XX.XX - - [26/Aug/2015:07:26:57 +0900] "GET /robots.txt HTTP/1.1" ...
[192.168.1.11: xxx-log] XX.XX.XX.XX - - [26/Aug/2015:07:27:02 +0900] "GET /xxx/xxx/xxx HTTP/1.1" ...
[192.168.1.10: xxx-log] XX.XX.XX.XX - - [26/Aug/2015:07:27:17 +0900] "POST /xxx/xxx/xxx HTTP/1.1" ...
[192.168.1.12: xxx-log] XX.XX.XX.XX - - [26/Aug/2015:07:27:29 +0900] "GET /xxx/xxx/xxx HTTP/1.1" ...
[192.168.1.13: xxx-log] XX.XX.XX.XX - - [26/Aug/2015:07:32:18 +0900] "GET /xxx/xxx/xxx HTTP/1.1" ...
[192.168.1.10: yyy-log] error: xxxxxxxx
[192.168.1.10: xxx-log] XX.XX.XX.XX - - [26/Aug/2015:07:32:26 +0900] "GET /xxx/xxx/xxx HTTP/1.1" ...
General usage is:
mixtail -example > config.yml
# modify config.yml as you want.
mixtail config.yml
Available options are following:
mixtail [options] config-file-path
options:
--example: Print an example of config file.
--version: Show version.
--help: Show this help.
If you don't want define user,pass or identity in config.yml, you can define them in external config file(./.mixtail.yml or ~/.mixtail.yml).
Example:
cat > ./.mixtail.yml <<EOT
default:
user: username
identity: path/to/key
EOT
# if you have defined above settings,
# you can ommit user,pass or identity in config.yml.
cat > ./config.yml <<EOT
input:
xxx-log:
type: ssh
host:
- 192.168.1.10
- 192.168.1.11
command: tail -f /tmp/test.log
EOT
