Data Mapping cfxdm - dm:fixcolumns

PreviousData Mapping cfxdm - dm:selectcolumnsNextData Mapping cfxdm - dm:mergecolumns

Last updated 3 years ago

dm: fixcolumns: This dm function allows the user to remove the special characters like @,. (dot) etc from a column name. If there is a special character in between a column name, it replaces it with an underscore (ex: First. Last to First_Last)

dm: fixcolumns syntax: It doesn't require any arguments. Just ingest the data into this tag/function using a pipe (-->)

Example 1:

Default dm: fixcolumns functionality is captured in this example.

Step 1: Create an empty dm_fixcolumns_example_1 using AIOps studio as shown in the below screenshot.

Step 2: Add the following pipeline code/commands into the above-created pipeline as shown in the below screenshot:

You can copy the below code into your pipeline and execute that in your environment. ##### This pipeline creates a set of records/dateset details coming from a vCenter ##### environment. This dataset includes datastore details, Folder name, guest_hostname, ##### guest_ip_address. ###### This pipeline uses dm fixcolumns to fix the column names that has special ###### characters and replace with '_' character for other operations. @dm:empty --> @dm:addrow datastore.1 = 'CFX-QA-Store-NFS-qnap' & Folder = '' & guest_full_name = 'CentOS 4/5/6/7 (64 bit)' & guest_hostname = 'test2.oia.cloudfabrix.com' & guest_ip_address = '10.95.134.17' & `VM Name` = 'test1' --> @dm:addrow datastore.1 = 'CFX-QA-Store-NFS-qnap' & Folder = 'User VMs' & guest_full_name = 'CentOS 4/5/6/7 (64 bit)' & guest_hostname = 'qa.oia.cloudfabrix.com' & guest_ip_address = '10.95.122.13' & `VM Name` = 'test2' --> @dm:addrow datastore.1 = 'ENG_ISOs,netapp-qa-nfs' & Folder = 'User VMs,Ravi-Pisupati,TestVMs' & guest_full_name = 'Ubuntu Linux (64 bit)' & guest_hostname = 'ubuntuqa' & guest_ip_address = '10.95.102.172' & `VM Name` = 'test3' --> @dm:addrow datastore.1 = 'datastore1 (6)' & Folder = 'Ravi-Pisupati' & guest_full_name = 'CentOS 4/5/6/7 (64 bit)' & guest_hostname = 'elkstack' & guest_ip_address = '10.95.121.218' & `VM Name` = 'test4' --> @dm:addrow datastore.1 = 'datastore1-198' & Folder = '' & guest_full_name = 'Microsoft Windows Server' & guest_hostname = 'spdnode.adwinstack' & guest_ip_address = '10.95.132.4' & `VM Name` = 'test5' --> @dm:addrow datastore.1 = 'netapp-dev-nfs-01' & Folder = 'User VMs,Ravi-Pisupati,TestVMs' & guest_full_name = 'CentOS 4/5/6/7 (64 bit)' & guest_hostname = 'localhost' & guest_ip_address = '10.95.103.115' & `VM Name` = 'test6' --> @dm:addrow datastore.1 = 'netapp-dev-nfs-01' & Folder = 'User VMs,Ravi-Pisupati,TestVMs' & guest_full_name = 'CentOS 4/5/6/7 (64 bit)' & guest_hostname = 'localhost' & guest_ip_address = '10.95.103.115' & `VM Name` = 'test7' --> @dm:addrow datastore.1 = 'netapp-dev-nfs-02' & Folder = 'CFX-Drama,Capri-Demo' & guest_full_name = 'CentOS 4/5/6/7 (64 bit)' & guest_hostname = 'democloudp' & guest_ip_address = '10.95.122.212' & `VM Name` = 'test8' --> @dm:addrow datastore.1 = 'netapp-dev-nfs-02' & Folder = 'CFX-Drama,Capri-Demo' & guest_full_name = 'CentOS 4/5/6/7 (64 bit)' & guest_hostname = 'ravip-v201-platform' & guest_ip_address = '10.95.122.216' & `VM Name` = 'test9' --> @dm:addrow datastore.1 = 'netapp-dev-nfs-02' & Folder = 'CFX-Drama,Capri-Demo' & guest_full_name = 'CentOS 4/5/6/7 (64 bit)' & guest_hostname = 'cfxautomatesvc' & guest_ip_address = '10.95.125.116' & `VM Name` = 'test10' --> @dm:fixcolumns

Step 3: Click verify button to make sure syntax and pipeline code is correct (as shown below)

Step 4: Click execute button and execute the pipeline. RDA will execute the pipeline without any errors (as shown below).

Step 5: RDA uses the dm fixcolumns function to replace special characters (dot, space, etc) with underscore character as shown in the following screenshot.
