check cpu usage and cpu wait
Cpu infos are taken from output of top command.
On higher cpu usage it can show processes that cause cpu waits and
with most cpu consumption.
SYNTAX:
$_self [options]
OPTIONS:
-a authentication params for snmpwalk/ snmpget to connect to target;
default: \"-v2c -c public\" (Snmpv2 with community string \"public\")
-h host to connect as hostname or ip address
-f FILE
read authentication from config file
default: \"/etc/icingaclient/snmp.cfg\"
-v detailed output
CONFIG FILE:
The config file can be multiline and has the syntax
[hostname]:[auth parameters]
The auth parameters set the version and all needed values to connect.
Snmp v2 uses a community string.
Snmp v3 is highly recommended (you should disable Snmp v2) and needs
a user and password.
Example:
server-01.example.com:-v 3 -l authnoPriv -a SHA -u snmpmonitor -A password-for-server-01
server-02.example.com:-v 3 -l authnoPriv -a SHA -u snmpmonitor -A password-for-server-02
EXAMPLE:
$_self -h server-01.example.com -v
Show Synology status of server-01 using connect data from /etc/icingaclient/snmp.cfg
$_self -h server-01.example.com -v -f /opt/somewhere/snmp.conf
Show Synology status of server-01 using connect data from custom config
