1. A computer implemented method of monitoring a communication network, the method comprising checking if remote electrical tilt equipment, RET, operates as intended to enable use of the RET in optimization actions, the method comprising
obtaining first information related to remote electrical tilt configurations deployed in the communication network;
obtaining second information related to cell documentation;
comparing the first and second information to identify mismatches between the first and second information, if any, wherein the mismatches indicate deviation in remote electrical tilt configuration; and
outputting an alarm concerning mismatches identified as a result of the comparison;
the method further comprising rearranging at least one of the first information and the second information before the comparison,
wherein said rearranging comprises grouping at least one of the first information and the second information by antenna instances.
