1. A sprinkler system comprising:
a fluid source;
a pipe coupled to the fluid source;
at least one sprinkler coupled to the pipe;
a sensor configured to measure a movement distance of a moving portion of the at least one sprinkler; and
a controller configured to:
increase a fluid pressure for the at least one sprinkler to a first pressure;
receive first sensor data, from the sensor, associated with the moving portion of the least one sprinkler, wherein the first sensor data includes a first movement distance of the moving portion of the at least one sprinkler; and
enact a first action based at least in part on the first movement distance being less than a threshold.
 
11. A method for sprinkler system diagnostics, the method comprising:
increasing, by a controller, a fluid pressure in a pipe to a first pressure, wherein the pipe is coupled to at least one sprinkler;
receiving, from a sensor, first sensor data associated with a moving portion of the least one sprinkler, wherein the first sensor data includes a first movement distance of the moving portion of the at least one sprinkler; and
enacting a first action based at least in part on the first movement distance being less than a threshold.
