A collecting tool of system metrics (CPU, Memory, Load, disks I/Os, Network traffic) to an InfluxDB server.
You can download the lastest version for GNU/Linux amd64 here.
To display all metrics without sending them to a server :
$GOPATH/bin/sysinfo_influxdb
To send metric to an InfluxDB server, only one time :
$GOPATH/bin/sysinfo_influxdb -h localhost:8086 -u root -p secret -d database
You can ommit -h, -u and -p if you use default settings.
By default, table are prefixed by the hostname, to change or disable the prefix, just do :
$GOPATH/bin/sysinfo_influxdb -P "" # Disable prefix
$GOPATH/bin/sysinfo_influxdb -P "koala"
To run in daemon mode (doesn't fork, just loop), use the -D option :
$GOPATH/bin/sysinfo_influxdb -D
To display data even if you send them to a server, use -v :
$GOPATH/bin/sysinfo_influxdb -D -h localhost:8086 -d database -v
Use the -i option to change the collect interval; this option alters the consistency of quantities displayed or sent (CPUs, network or disks I/Os) : the amount of outgoing packets in 1 minute is not directly comparable to the same amount outgoing in 1 second when saved in the same table. For example, to collect statistics each minute :
$GOPATH/bin/sysinfo_influxdb -i 1m
To change data collected, use the -c option with one or more metrics type (cpus, mem, swap, uptime, load, network, disks) like this :
$GOPATH/bin/sysinfo_influxdb -c cpus # Collect only CPUs related statistics
$GOPATH/bin/sysinfo_influxdb -c load,cpus,disks # Collect load average, CPUs and disks I/Os statistics
On hardened kernel, you must be allowed to read /proc/net/dev in order to collect networking statistics.
