-## interpolation
+## StatsD examples
-~~If you send just one value to statsd, you will notice that the chart is created but no value is shown. The reason is that Netdata interpolates all values at second boundaries. For incremental values (`counters` and `meters` in statsd terminology), if you send 10 at 00:00:00.500, 20 at 00:00:01.500 and 30 at 00:00:02.500, Netdata will show 15 at 00:00:01 and 25 at 00:00:02.~~
+### Python
+
+It's really easy to instrument your python application with StatsD, for example using [jsocol/pystatsd](https://github.com/jsocol/pystatsd).
+
+```python
+import statsd
+c = statsd.StatsClient('localhost', 8125)
+c.incr('foo') # Increment the 'foo' counter.
+for i in range(100000000):
+ c.incr('bar')
+ c.incr('foo')
+ if i % 3:
+ c.decr('bar')
+ c.timing('stats.timed', 320) # Record a 320ms 'stats.timed'.
+```
-~~This interpolation is automatic and global in Netdata for all charts, for incremental values. This means that for the chart to start showing values you need to send 2 values across 2 flush intervals.~~
+You can find detailed documentation in their [documentation page](https://statsd.readthedocs.io/en/v3.3/).
-~~(although this is required for incremental values, Netdata allows mixing incremental and absolute values on the same charts, so this little limitation [i.e. 2 values to start visualization], is applied on all Netdata dimensions).~~
+### Javascript and Node.js
-(statsd metrics do not lose their first data collection due to interpolation anymore - fixed with [PR #2411](https://github.com/netdata/netdata/pull/2411))
+Using the client library by [sivy/node-statsd](https://github.com/sivy/node-statsd), you can easily embed StatsD into your Node.js project.
