During the conversion of pnp4nagios files to the Round Robin Database (RRD) format, you may face these errors.

LAST TESTED ON CHECKMK 2.1.0P1

'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'

How to debug

Let's modify the command to receive more debug output:

OMD[mysite]:~$ cmk -vv --debug --convert-rrds --delete-rrds RRD8040
RRD8040:
Traceback (most recent call last):

  File "/omd/sites/rrd/lib/python/cmk_base/cee/rrd.py", line 728, in find_pnp_rrds
    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]:~$ find ~/var/pnp4nagios/perfdata -name "*.xml" | while read xmlfile; do grep "NAGIOS_AUTH_HOSTNAME" $xmlfile >/dev/null || ls $xmlfile; done

If I check each of these files, the files look really different. So either the files are corrupt, or they are not in the right format:

Probably, the filesystem ran full during the conversion. The only solution is to delete these files and run the conversion again!

How to debug

Let's modify the command to receive more debug output:

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

    old_config_raw = rrdtool.info([rrd_file_path])
TypeError: Element 0 in argument 0 must be str

And here we go: The issue is 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

How to debug

In the first line of the cmk-update-config -vv --debug output there is already a hint to the corresponding host:

Loading autochecks from /omd/sites/mysite/var/check_mk/autochecks/MYHOST.mk


Please fetch that name and remove the .mk suffix. Now you have the Hostname. In my case it's MYHOST.


Now you can use xmllint to debug that:

OMD[mysite]:~$ xmllint  -noout --format var/pnp4nagios/perfdata/MYHOST/*xml
var/pnp4nagios/perfdata/MYHOST/Filesystem_E__.xml:1: parser error : Document is empty

^

It seems that there is one xml file with no corresponding rrd file and this xml file is also empty. Please remove that file and run cmk-update-config -vv --debug again

xml.etree.ElementTree.ParseError: unclosed token: line 114, column 0

How to debug

In the first line of the cmk-update-config -vv --debug output, there is already a hint to the corresponding host:

Loading autochecks from /omd/sites/mysite/var/check_mk/autochecks/MYHOST.mk

Please fetch that name and remove the .mk suffix. Now you have the Hostname. In my case, it's MYHOST.

Now you can use xmllint to debug that:

OMD[mysite]:~$ xmllint  -noout --format var/pnp4nagios/perfdata/MYHOST/*xml
var/pnp4nagios/perfdata/MYHOST/Filesystem_F__.xml:114: parser error : expected '>'
</N

It seems like the problem is in row 114 with a missing '>'. Let's check the xml file.

OMD[mysite]:sed -n '2p; 114p' var/pnp4nagios/perfdata/MYHOST/Filesystem_F__.xml 
<NAGIOS>
</N

And here we go. Row 114 seems to be incomplete.
Please add "</NAGIOS>" and save the file.


The file should now look like this:

OMD[mysite]:~$ sed -n '2p; 114p' var/pnp4nagios/perfdata/MYHOST/Filesystem_F__.xml 
<NAGIOS>
</NAGIOS>

If you now run cmk-update-config -vv --debug again, there should be no error
