    Description

      Description

      A customer cited the OM hardware requirements page which states 15 GB RAM for the OM application plus 15 GB for a co-hosted backup daemon, however the actual memory use for their OM application was ~40 GB plus ~13 GB for the backing mongod servers, plus ~17 GB for the backup daemon mongod:

        PID USER    PR NI VIRT  RES SHR S %CPU%MEM  TIME+   COMMAND
       1094 mongodb 20 0 9371m 6.4g 17m S 3.9 2.5 385:45.94 mongod
       7276 mongodb 20 0 3604m 1.6g 10m S 3.9 0.6 224:20.54 mongod
       2797 mongodb 20 0 40.2g 3.2g 11m S 1.9 1.3 304:48.43 mms-app
       3458 mongodb 20 0 11.4g 8.5g 14m S 1.9 3.4 164:58.07 mongod
      18974 mongodb 20 0 16.9g 15g  15m S 1.9 6.1 102:23.26 mongod
      

      Customer requests this documentation be updated to more accurately estimate Ops Manager application server memory use expectations.
