Practical MongoDB –PDF description
The “opcounters” section shows the number of operations of each type. In order to find out if there’s any problem, you should have a baseline of these operations. If the counters start deviating from the baseline, this indicates a problem and will require taking action to bring it back to the normal state.
The “asserts” section depicts the number of client and server warnings or exceptions that have occurred. If you find a rise in such exceptions and warnings, you need to take a good look at the logfiles to identify if a problem is developing. A rise in the number of asserts may also indicate a problem with the data, and in such scenarios MongoDB validate functions should be used to check that the data is undamaged.
