### Graphite integration
|
|
|
|
Example screen: 
|
|
|
|
We could store pps/bps/flow number for top 7 (could be configured) host in incoming and outgoung directions. In addition to this we export total pps/bps/flow number which flow over FastNetMon.
|
|
|
|
Configuration from FastNetMon side is very simple, please put following fields to /etc/fastnetmon.conf:
|
|
```bash
|
|
graphite = on
|
|
graphite_host = 127.0.0.1
|
|
graphite_port = 2003
|
|
graphite_prefix = fastnetmon
|
|
```
|
|
|
|
### Install Graphite Debian 8 Jessie
|
|
|
|
First of all, please install all packages:
|
|
```bash
|
|
apt-get install -y python-whisper graphite-carbon
|
|
```
|
|
|
|
Whisper - it's database for data. Graphite - service for storing and retrieving data from database.
|
|
|
|
Install web frontend:
|
|
```bash
|
|
apt-get install -y graphite-web
|
|
```
|
|
|
|
Create database, specify login/password and email here:
|
|
```bash
|
|
graphite-manage syncdb
|
|
```
|
|
|
|
Specify your timezone in file /etc/graphite/local_settings.py on line TIME_ZONE.
|
|
|
|
Change owner:
|
|
```bash
|
|
chown _graphite:_graphite /var/lib/graphite/graphite.db
|
|
```
|
|
|
|
Run it with apache:
|
|
```bash
|
|
apt-get install -y libapache2-mod-wsgi apache2-mpm-prefork
|
|
cp /usr/share/graphite-web/apache2-graphite.conf /etc/apache2/sites-available/graphite-web.conf
|
|
a2dissite 000-default.conf
|
|
a2ensite graphite-web
|
|
a2enmod wsgi
|
|
```
|
|
|
|
Enable load on startup:
|
|
```bash
|
|
systemctl enable apache2.service
|
|
systemctl restart apache2.service
|
|
```
|
|
|
|
Open site:
|
|
http://ip.ad.dr.es
|
|
|
|
Put test data to Graphite:
|
|
```echo "test.bash.stats 42 `date +%s`" | nc -q0 127.0.0.1 2003```
|
|
|
|
If you have issues with Carbon like this:
|
|
```bash
|
|
/etc/init.d/carbon-cache start
|
|
* Starting Graphite backend daemon carbon-cache Traceback (most recent call last):
|
|
File "/usr/bin/carbon-cache", line 32, in <module>
|
|
run_twistd_plugin(__file__)
|
|
File "/usr/lib/python2.7/dist-packages/carbon/util.py", line 90, in run_twistd_plugin
|
|
config.parseOptions(twistd_options)
|
|
File "/usr/local/lib/python2.7/dist-packages/twisted/application/app.py", line 619, in parseOptions
|
|
usage.Options.parseOptions(self, options)
|
|
File "/usr/local/lib/python2.7/dist-packages/twisted/python/usage.py", line 270, in parseOptions
|
|
raise UsageError("Unknown command: %s" % sub)
|
|
twisted.python.usage.UsageError: Unknown command: carbon-cache
|
|
```
|

Some useful graphics for Graphite.

|
Total load:
|
|
```bash
|
|
fastnetmon.incoming.pps
|
|
fastnetmon.outgoing.pps
|
|
|
|
fastnetmon.incoming.mbps
|
|
fastnetmon.outgoing.mbps
|
|
```
|
|
|
|
Top talkers:
|
|
```bash
|
|
highestMax(fastnetmon.*.outgoing.average.pps, 10)
|
|
highestMax(fastnetmon.*.outgoing.average.mbps, 10)
|
|
highestMax(fastnetmon.*.incoming.average.pps, 10)
|
|
highestMax(fastnetmon.*.incoming.average.mbps, 10)
|
|
```
|
|
|
|
Also I recommend to configure Graphite this way.
|
|
|
|
For big networks please enlarge number of created file in /etc/carbon/carbon.conf:
|
|
```bash
|
|
MAX_CREATES_PER_MINUTE = 5000
|
|
```
|
|
|
|
And if you want to store data every 5 seconds for 1 months please do following _before_ starting collection to Graphite in file /etc/carbon/storage-schemas.conf:
|
|
```bash
|
|
[default_5sec_for_1month]
|
|
pattern = .*
|
|
retentions = 5s:31d
|
|
```
