The question was asked on the devel list earlier if there was a way to check all one's packages for their status in pkgdb and whether they are in anitya.

So I just cooked up quickly a small script to do just that, it retrieves all the packages in pkgdb that you are point of contact or co-maintainer and tells you if its monitoring flag is on or off in pkgdb and if it could be found in anitya.

For example for me (partial output):

$ python pkgs_not_in_anitya.py pingou
   * point of contact
     R-ALL                                Monitor=False   Anitya=False
     R-AnnotationDbi                      Monitor=False   Anitya=False
     ...
     guake                                Monitor=True    Anitya=True
     igraph                               Monitor=False   Anitya=False
     jdependency                          Monitor=True    Anitya=True
     libdivecomputer                      Monitor=True    Anitya=True
     metamorphose2                        Monitor=False   Anitya=False
     packagedb-cli                        Monitor=False   Anitya=False
     ...
   * co-maintained
     R-qtl                                Monitor=False   Anitya=False
     fedora-review                        Monitor=True    Anitya=True
     geany                                Monitor=True    Anitya=True
     geany-plugins                        Monitor=True    Anitya=True
     homebank                             Monitor=True    Anitya=True
     libfprint                            Monitor=True    Anitya=True
     ...
