We are looking at expanding into LM Logs and I am wondering are there any other hidden alert tokens? We are looking at what structure of the message we can send, and there feels to be a lack of items for LM Logs. Is there a way to pull out some of the log fields as part of the message? The closest we found so far is ##logMetaData## which gives us a json string of our custom fields. For future parties here is a little more detail. ##alerttype## logAlert ##datapoint## Log Pipeline Alert Condition Name ##datasource## LM Logs ##dsdescription## Raw Log Value ##dsidescription## Raw Log Value ##instance## Log Pipeline Name ##threshold## Log Pipeline Alerting Condition ##logMetaData## Log metadata fields included in alert from Pipeline Alert Conditions41Views1like0CommentsLogSource Resource Mapping Confusion
I have a ticket opened but hoping to get a quicker response here. I am using LogSources but since we are an MSP with multiple clients, there seems to be an issue syslog's are being mapped to other client devices that have the same IP because I'm using IP=system.hostname as the mapping. I have even pointed all the duplicate IPs to their respective syslog collector and it still maps wrong. Am I doing something wrong or is the system not smart enough to know that it came on this collector, therefore I should only map it to resources monitored by that collector? Is there a way I can use AND logic with the Token mapping for _lm.collectorId = system.collectorid? Thanks in advance.Solved102Views8likes7CommentsLM Logs - Alerting
Hello, Just wanted to ask if there is a way to have alerting on multiple lets say IP addresses in a similar log message but not have it spam our ticketing system? Log Message 1 - 1.1.1.1 is down Log Message 2 - 2.2.2.2 is down Log Message 3 - 1.1.1.1 is down I want to be able to alert on 1.1.1.1 being down and suppress it for a day on duplicate alerts but if I have a alert query for "is down" then 2.2.2.2 will also get suppressed for a whole day as well when its a whole separate device/alert. I would also not be able to add all lets say 50 IP addresses that may alert as their own alert condition. Is there a way or is LM Log too limiting right now?61Views2likes1CommentLM Logs multiple capture group parsing
Ok, this is cool. I have some log data that has structured data in it (some text, then a python list of strings). I had started building out a parse statement for each member of the list, then thought I’d try just making multiple capture groups and naming multiple variables after the as fanboy. Turns out it completely works. It parses each capture group into the corresponding column with a single parse statement. I was halfway through writing out a feature request when I figured I’d give it a try only to discover that it completely works. Nice job LM Logs guys.116Views14likes2CommentsHas anybody noticed the flaw in LogSource logic?
So LogSources have a couple purposes: They allow you to filter out certain logs. I’m not sure the use case here since the LogSource is explicitly including logs. Maybe the point is to allow you to exclude certain logs that have sensitive data. No masking of data, just ignore the whole log. Not clear if the ignored logs are still in LMLogs or if they get dumped entirely. They allow you to add tags to logs. This is actually pretty cool. You can parse out important info from the log or add device proeprties to the logs. This means you can add device properties to the log that can be displayed as a separate column, or even filtered upon. Each of our devices has a customer property on it. This means i can add that property to each log and search or filter by customer. Device type, ssh.user, SKU, serial number, IP address, the list is literally endless. They allow you to customize which device the logs get mapped to. You can specify that the incoming log should be matched to device via IP address, or hostname, or FQDN, or something else. The documentation on this isn’t exactly clear, but that actually doesn’t matter because… The LogSources apply to logs from devices that match the LogSource’s AppliesTo. Which means the logs need to already be mapped to the device. Then the LogSource can map the logs to a certain device. Do you see the flaw? How is a log going to be processed by a LogSource so it can be properly mapped to a device, if the LogSource won’t process the log unless it matches the AppliesTo, which references to the device, to which the logs haven’t yet been mapped? LogSources should not apply to devices. They should apply to Log Pipelines.Solved248Views18likes4CommentsLM Logs parser conditional formatting operator
Submitted to LM Feedback under the title “LM Logs parser colorization based on criteria” As an engineer who is trying to see how certain logs relate to other logs, it would be helpful if I could highlight specific logs in context with other logs by using an advanced search operator to colorize certain logs that meet a certain criterion. For example, I run this query often: "PagerDuty Ticket Creation" | parse /(.*) (SUMMARY|ERROR|INFO|DEBUG): (.*)/ as Script, Severity, Msg One of the fields I parse is the Severity, which as you can see can have values of SUMMARY, ERROR, INFO, or DEBUG. It would be nice if I could add an operator to the query that would let me colorize rows based on the value of the parsed Severity column (Severity just in this case; for the general case, any expression on any column). For example, I'd like to run the query: "PagerDuty Ticket Creation" | parse /(.*) (SUMMARY|ERROR|INFO|DEBUG): (.*)/ as Script, Severity, Msg | colorize Severity == "ERROR" as orange | colorize Severity ~ /SUMMARY|INFO/ as green The result would be that rows in the table that have a value of "ERROR" would have a background color of orange (a muted orange) and rows in the table that have a value of "SUMMARY" or "INFO" would be colored green. Since the DEBUG logs don't match any colorization operator, they would have the default color of white. It might be handy if one *or* two colors could be passed, allowing me to change the color of the text and the background, or just the background. It would be ok if I could only choose from a set list of colors, but it would be great if I could specify an RGBA color.34Views12likes0Comments
