During the conversion of pnp4nagios files to the rrd format, you may face this errors:
'NoneType' object has no attribute 'text'
OMD[mysite]:~$ cmk -v --convert-rrds --delete-rrds RRD8040
RRD8040:
HOST: RRD8040
ERROR: 'NoneType' object has no attribute 'text'
Let's modify the command to receive more debug output:
It looks like we have some xml files without "NAGIOS_AUTH_HOSTNAME"
To find the corrupted files, you can grep for "NAGIOS_AUTH_HOSTNAME" , save the result to a list and compare this list with all xml files
OMD[mysite]:~/var/pnp4nagios/perfdata/RRD8040$ ls |grep ".*.xml" |sort >~/tmp/xml OMD[mysite]:~/var/pnp4nagios/perfdata/RRD8040$ grep -ril "NAGIOS_AUTH_HOSTNAME" |sort >~/tmp/xml1 OMD[mysite]:~/var/pnp4nagios/perfdata/RRD8040$ diff ~/tmp/xml ~/tmp/xml1 64d63 < Volume_BILDER_BILDER.xml 87d85 < Volume_UNIX_DATA_01_fs_size.xml 100d97 < Volume_nasstore01.BILDER_fs_size.xml
If I check each of these files, the files are looking really different. So either the files are corrupt, or they are not in the right format:
The only solution is to delete these files and run the conversion again!

And here we go: The issue are the "ü" characters in the service name. This only affects Checkmk 1.6. With Checkmk >2.0 we changed the behavior of non-ASCII Services names (Werk #13711)
Solutions:
- If it's related to a builtin Check → please open a ticket via the customer portal
- If it's a customization → You need to change the service description of the service, do a rediscovery and move the old pnp4nagios files to the new ones
- The easiest way is to con
