A collecting tool of system metrics (CPU, memory, load, disks I/Os, network traffic) to an InfluxDB server.
This project mainly relies on gosigar, so it's compatible with GNU/Linux and MacOS system, but not with Windows yet.
You can download the lastest version for amd64/x86/arm on gobuild website.
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
Password can also be read from a file if you don't want to specify it in CLI (-p is ignored if specified with -s) :
$GOPATH/bin/sysinfo_influxdb -h localhost:8086 -u root -s /etc/sysinfo.secret -d database
You can ommit -h, -u, -p or -s if you use default settings.
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 preserves the consistency of quantities displayed or sent (CPUs, network or disks I/Os) : so you can store in the same table the amount of outgoing packets in 1 minute to the same amount outgoing in 1 second (use -C option to alter the consistency factor). 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 (cpu, cpus, mem, swap, uptime, load, network, disks, mounts) like this :
$GOPATH/bin/sysinfo_influxdb -c cpus # Collect only CPUs related statistics by CPU core
$GOPATH/bin/sysinfo_influxdb -c load,cpu,disks # Collect load average, global CPU and disks I/Os statistics
$GOPATH/bin/sysinfo_influxdb -c mem,mounts # Collect memory metrics and local filesystems usage
On Linux hardened kernel, you must be allowed to read /proc/net/dev in order to collect networking statistics.
