As far as I can see in Xymon 4.3.30 selinux is already modified by the Xymon
RPM to cater for this:

# rpm -qf /usr/share/doc/xymon-4.3.30/xymon.te

Looking at the file shows:

#============= ping_t ==============
allow ping_t { tmp_t initrc_tmp_t var_lib_t }:file { getattr write };

Running 4.3.30 on CentOS 7 we have had to make no changes to selinux.
