Query on SIEM parsing

Hi All,We are managing Crowdstrike NGSIEM  in our network and all the data sources are routed to Cribil and from Cribil , we are forwarding the logs to NGSIEM. Data source → Cribil →  NGSIEM I understand , we require parsers in NGSIEM to read the relevent logs received from the  datasources but I wish to know ,is there any parser concept present in cribil to onboard the logs from the different datasources.

How do I create a REST API Collector that needs to reference a dynamic bearer token?

This is an example of how we can reference a value provided by Discover Type HTTP Request in the REST API Collector which will correctly save a bearer token value which will expire (default time 5 minutes) using a named Token attribute: token, Authorization header `Bearer $(token)` and Authentication expression `Bearer $(token)` The initial authorization request:curl -X POST 'http://localhost:9000/api/v1/auth/login' -H "Content-Type: application/json" -d '{ "username": "admin", "password": "<password value here>" }' Run a Discover request to generate a bearer token: The above request will return a value something like: {"token":"abcdefgUNIQUEPASSWORDTOKENabcdefgUNIQUEPASSWORDTOKENabcdefgUNIQUEPASSWORDTOKENabcdefgUNIQUEPASSWORDTOKENabcdefgUNIQUEPASSWORDTOKENabcdefgUNIQUEPASSWORDTOKEN","forcePasswordChange":false} The Collect layer will use the information pulled during discover to pull the following: The Encode operation is not necessary but provided for illustration purposes.‘ite

Is there a list of links for cribl upgrade files?

Had a situation where the automatic upgrade was not working, so had to manually upgrade.From the logs it was trying to download ARM version not X64 version.Fortunately managed to figure out the correct weblink by changing the file name slightly: https://cdn.cribl.io/dl/4.10.1/cribl-4.10.1-45136dbb-linux-x64.tgz.Are these links listed anywhere on the cribl website, or how would we manually upgrade?

filter expresion and route order

Hello,I noticed a strange thing maybey anyone can explain.I have 3 syslog sources: syslog:514: ,syslog:51402: and syslog:51403:Three routes for these sources, each with a different pipeline attached. The order off the routes are 514 then 51402 and at last 51403.The filter in de routes are __inputId.startsWith('syslog:514:') &&  __srcIpPort.includes('10.10.1.112')__inputId.startsWith('syslog:51402:') && __srcIpPort.includes('10.10.1.112')__inputId.startsWith('syslog:51403:')&&  __srcIpPort.includes('10.10.1.112')(same host with different syslog outputs)In this order the 514 port gets a load off events, the 51402 lesser and teh 51403 nothing. That surpised me because when a check the source side i can capture 51403 events from this sourceip.For test i moved the 514 route after the 51403 route. Just a feeling. but what??.. the 51403 gets suddenly l the events it was missing. And here it gets strange. Just as if the 514 filter takes al the events from the 51403. But

Cribl Edge (standalone): Windows Metrics - Splunk, do not result in actionable information

I am new with Cribl.Cribl Edge (standalone, installed on Windows 10 laptop for test/evaluation): Windows Metrics do not return actionable information when forwarding to a standalone Splunk Enterprise instance. What am I doing wrong or what I am missing here?Windows Eventlog cribl-source is correctly received in json. But adding the Windows Metrics cribl-source to the same (working) Splunk Destination (default forwarding to port 9997) it shows:All relevant metric_names seems to be received correctly, but no Values to find. Besides, do not understand the metric_type "g". I would expect a value-field in bytesI have tried many things sofar, including Cloud Stream, searching in the docs and and start some basic first lessons on Cribl Universty. Neither an overall and understandable Google search explanation about type g. Stuck now!Does somebody has a clue, suggestion, tip or direction to search in other sources?ThanksAshleyP

Distributed deployment planning with compressing g-zip Destination?

Hello everyone,I have the following problem. I'm designing a distributed deployment. I have to create an environment for data reduction but before that I need to send the data to a blob storage, for compliance reason, as you can imagine. Now, all of these is achieved but I have some doubts. When I use the Azure blob storage as only destination, all the 100% of the data goes in there but, the Monitoring Page, is telling me that the data that comes in are the same as the data that goes out (sometimes, the data that goes out are even more), even with compression enable. As said, I have the g-zip compression enabled on the Azure Destination page. I've checked the storage and I found out that the data are really compressed. So, my point is the following: when I try to estimates the possible number of workers and their capabilities, should I trust the monitoring page and consider DATA IN = DATA OUT (since the data is not processed by any pipeline at all) or I can consider the quantity of byt

Updating Windows Agents Through the UI

Hi,We are currently working on updating our Cribl Edge Agents. While our Linux agents successfully auto-update through the UI, we are encountering issues with our Windows agents. Specifically, the Windows agents display an error during the download process and fail to update.Manual updates are possible by logging into the system and running the update script; however, the UI-based update consistently fails. We have confirmed that port 4200 is open, and there are no indications of blocked or dropped traffic. Additionally, all platform-specific packages, including the corresponding hash files, have been prepared and placed in the appropriate Cribl temporary directory.Given these conditions, what could be causing this issue?

Having hard luck with parsing logs - tips?

Hi, I have gone through the cribl university user and admin courses and setting up the product is quite easy however am constantly stuck trying to parse or extract strings of data into fields so that we can search or use the information.For systems which send in JSON or CSV it is very simple, however most of ours are embedded Linux or network devices which give something like the following:<183> 02/06/2025:00:24:20 GMT NYDC1VPX01-DMZ 0-PPE-0 : default SSLLOG SSL_HANDSHAKE_SUCCESS 9838002 0 : SPCBId 33168208 - ClientIP 10.1.1.130 - ClientPort 57486 - VserverServiceIP 10.200.80.80 - VserverServicePort 443 - ClientVersion TLSv1.2 - CipherSuite "TLS1-AES-256-CBC-SHA" - Session New - HandshakeTime 47 msShowWhat combination of functions can split this out into fields such as hostname, clientip, clientport, etc.I have tried using ChatGPT to help and can get regex and grok expressions from the AI however these don't work when applying to cribl. I don't see many questions on this topic

Crowdstream - Bytes out size doubled

Hi EveryoneWe have integrated Azure Storage Account and Azure Application Gateway with CrowdStream (Cribl Stream) via EventHub. Since logs are in nested JSON format, we used unroll function to convert them into individual events before forwarding them to CrowdStrike NGSIEM.Currently, we are observing that Bytes Out size is twice that of Bytes In. While we understand that event count should double, our concern is why Bytes Out size is also doubling compared to Bytes In. Additionally, we have not observed any duplicate events in CrowdStrike NGSIEM.

Updating a lookup table with a pipeline function

I read that Cribl has the ability to update lookup tables using REST API and with a search string, but I'm looking for a way to do it during the processing stage. Is this possible? I see a Redis function and read something about that. If the values go there, is there a way to automatically lookup the results?

Having difficulty translating API header to Cribl

Hello,I'm new to Cribl stream and am having difficulty translating the API spec from the documentation. I can get all the curls working fine, but I don't know how they translate to cribl. For example, if I'm trying to use cribl for this type of curl:curl --location --request GET 'https://public-api.cloud.meater.com/v1/devices' \--header 'Authorization: Bearer <JWT>'What would my discover and collect headers look like to include the "Authorization: Bearer <JWT>?Cribl is authenticating correctly (I managed to figure that out), but all my requests result in a 400. My authorize expression is `Bearer ${token}`Any help/insight would be greatly appreciated.

A working example of a script in Stream - Help me keep track of my goats

I am attempting to record which server logs are being collected, e.g. last seen, and I haven't found that capability yet. I am thinking I need something custom, maybe write to a file or a lookup. The cribl documentation doesn't provide much in the way of specifics when it comes to implementing scripts, except an ominous warning. I am new to the product and any help is greatly appreciated.
