OML FAQ¶

I'm seeing lots of zeroes in my measurement database!¶

The OML client library has two ways of generating outputs from its filters: sample-based output and interval-based output. If you use interval-based filtering, the client library generates a measurement from every filter at the interval you specify. If there were no samples injected into a measurement point during that interval, any filters attached to that measurement point will still generate a "null" measurement output. For numeric types this is always a zero value. Check if you are using interval filtering and check how often your application is calling omlc_inject(3).
