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:

OMD[mysite]:~$ cmk -vv --debug --convert-rrds --delete-rrds RRD8040
RRD8040:

    xmlinfo = parse_pnp_xml_file(host_dir + "/" + xml_file)

    'host': root.find('NAGIOS_AUTH_HOSTNAME').text,
AttributeError: 'NoneType' object has no attribute 'text'


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!

TypeError: Element 0 in argument 0 must be str

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
  • No labels
