Troubleshooting and Limitations – Host Connection by SNMP Job

Search for	Example	Results
A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`

Problem: Following the run of the Host Connection by SNMP or Host Networking by SNMP jobs, many warning messages are displayed:

Detected multiple updates in bulk - found attribute:
'interface_description' on current CIT: 'interface'

These messages can be safely ignored. To prevent the messages being displayed, you can change the multipleUpdateIgnoreTypes parameter in the globalSettings.xml file:

<!--multipleUpdateIgnoreTypes
- don't check multiple updates for the following types-->
<property name="multipleUpdateIgnoreTypes">
process,clientserver,node</property>

Add the interface CIT to this list of CITs to be ignored.

Problem: Host connection discovery uses the following workflow: Host Connection by Shell, then Host Connection by WMI and then Host Connection by SNMP. Therefore, if Host Connection by Shell is successful, neither of the following jobs complete. Also, if Host Connection by WMI is successful, Host Connection by SNMP does not complete.

Solution: To skip this restriction, change the Trigger Query for these jobs:

Select Host Connection by SNMP.
Select the Properties tab.
Delete the Trigger Query ip_with_snmp_or_without_host.
Click the button in the Trigger Query section to create a new Trigger Query. The Choose Discovery Query dialog box appears.
Select ip from the list and click OK.
