Set the value of hostName to value of 0, else In pseudocode, I am attempting to perform: if the length of hostName is 0, then I only have one field displaying this issue, so I didn't use the foreach as in the example, but this is the adaptation I tried to use for my case |eval hostName=if(len(hostName)=0, 0, hostName)īut that just produces a literal 0 in my output using that coalesce snippet I provided above. From there, my coalesce will work as intended. What I think I want to accomplish is look for instances of 'hostName' where the length is zero. I found a Splunk Community Post explaining some of this, but as a noob, I am having a problem extending this to my particular problem. When I look at the raw events, I see that 'hostName' looks like: "hostName": "" Unfortunately, I am finding in many cases 'hostName' is not null, but rather 0 length which isn't the same as null which foils my coalesce. So I'm happy to use any of the fields in my example in order to do so. But as long as I can identify it, that is all that matters to me. This is necessary because I am looking at some data that sometimes doesn't have a hostname (presumably because not in DNS). I am trying to work with some data and I was trying to use the coalesce feature to do something like this: eval asset=coalesce(hostName,netbiosName,ip,macAddress)
