The BESIII detector is a magnetic spectrometer operating at BEPCII, a
double-ring e+e- collider with center-of-mass energies between 2.0 and
4.6 GeV and a peak luminosity $10^{33}$ cm$^{-2}$ s$^{-1}$. The event rate
is about 4 kHz after the online event filter (L3 trigger) at J/$\psi$

The BESIII online data quality monitoring (DQM) system is used to
monitor the data and the detector in real time using full
reconstructed data. It is a essential supplement to the DAQ
monitoring, which using unprocessed data directly from the detector. I
will give the review of the BESIII DQM system. The system is designed
to be weak coupled to the DAQ online system, so it can be developed
under the offline environment freely. The system includes the data
server, which is used to get data from DAQ, the reconstruction
processes for the data reconstruction, the histogram server, which is
used to collect all histograms from all reconstruction processes, and
the error handle of itself, and so on.
