Func common modules and APIs

Func common modules and APIs

1. Func provides a very rich range of functional modules, including:

Commandmodule (Execute command)

Copyfilemodule (copy file)

Cpumodule (CPU information)

Diskmodule (disk information)

Filetrackermodule (file tracking)

Iptablesmodule (iptables Management)

Mountmodule (Mount Mount)

Nagiosservermodule (Nagios Management)

Networktest (Network test)

Processmodule (Process Management)

Sysctlmodule (sysctl Management)

Snmpmodule (SNMP information management) and so on:

See more modules: https://fedoraproject.org/wiki/Infrastructure/Fedorahosted-retirement

Command line call module format:

func< target host >call<module_name (module name) ><method_name (method name) ><module_args (module parameter) >

For example, run "df–m" to view the managed side memory, such as:

[[Email protected] ~]# func compute call command Run "df-m"

(' Compute ',

[0,

  ' filesystem              1M-blocks  Used Available use% mounted on\n/dev/mapper/centos-root    459828  2131    457697& nbsp;  1%/\ndevtmpfs                      3861     0      3861    0%/dev\ntmpfs                         3871     0      3871   0%/dev/shm\ntmpfs                         3871    57       3815   2%/run\ntmpfs           & NBsp;            3871     0       3871   0%/sys/fs/cgroup\n/dev/sda1                      494   184        311  38%/boot\ntmpfs                          775     0        775   0%/run/user/0\n ',

‘‘])

Note: [[email protected] ~]# func "*" Call command Run "df-m" separate "*" for all controlled end

[[Email protected] ~]# func "Com*ute?" Call command Run "df-m" here "*" stands for any number of characters. “？ "Represents a single arbitrary character

Func "compute1;compute2" call command Run "df-m" multiple target hosts are separated using semicolons
