InfluxDB integration
InfluxDB is a very fast time series database written in Go language.
To start with this guide, please install InfluxDB from these binary packages.
Then we should enable graphite protocol emulation in configuration file: /etc/opt/influxdb/influxdb.conf As well enable batch for avoid metric loss under load, and add templates for converting graphite metrics to InfluxDB measurements, with its proper tags.
[[graphite]]
enabled = true
bind-address = ":2003"
protocol = "tcp"
consistency-level = "one"
separator = "."
batch-size = 5000 # will flush if this many points get buffered
batch-timeout = "1s" # will flush at least this often even if we haven't hit buffer limit
templates = [
"fastnetmon.hosts.* app.measurement.cidr.direction.function.resource",
"fastnetmon.networks.* app.measurement.cidr.direction.resource",
"fastnetmon.total.* app.measurement.direction.resource"
]
And disable Graphite daemons if you use they before:
systemctl stop carbon-cache
And start InfluxDB:
systemctl restart influxdb
You will got web frontend on 8083 port and query API interface on 8086.
Then we need to enable metrics export in /etc/fastnetmon.conf configuration file:
graphite = on graphite_host = 127.0.0.1 graphite_port = 2003 graphite_prefix = fastnetmon
And apply changes to configuration file:
systemctl restart fastnetmon
Finally you could query data from InfluxDB with CLI tool /opt/influxdb/influx:
Connected to http://localhost:8086 version 0.9.3-nightly-c2dbf16 InfluxDB shell 0.9.3-nightly-c2dbf16 > use graphite Using database graphite > show measurements name: measurements ------------------ hosts networks total > > select mean(value) from networks where direction = 'incoming' and resource = 'bps' group by * name: networks tags: app=fastnetmon, cidr=10.20.30.40_24, direction=incoming, resource=bps time mean ---- ---- 1970-01-01T00:00:00Z 408540.85148584365
Then you could install Grafana and try our nice predefined dashboards for FastNetMon
