Stream

I have verified that I can list the directories using the AWS CLI with the following command:aws s3 ls s3://cisco-managed-us-east-2/my_directory_prefix/I can pull the logs to my local directory using the following command:aws s3 sync s3://cisco-managed-us-east-2/my_directory_prefix/dnslogs/ C:\umbrella_logs\However, I am unable to pull them using the Umbrella S3 Collector in Cribl Stream locally hosted. Any ideas on what I could do differently?Here are my settings for the Cribl S3 collector with the personalized info redacted:{ "type": "collection", "ttl": "4h", "removeFields": [], "resumeOnBoot": false, "schedule": { "cronSchedule": "*/5 * * * *", "maxConcurrentRuns": 1, "skippable": true, "run": { "rescheduleDroppedTasks": true, "maxTaskReschedule": 1, "logLevel": "info", "jobTimeout": "0", "mode": "run", "timeRangeType": "relative", "timestampTimezone": "UTC", "timeWarning": {}, "expression": "true", "minTaskSize": "1MB", "maxTaskSize": "10MB" }, "enabled": false }, "streamtags": []

Hi all i am trying to upload few packs into stream leader using files but getting below sample error Error while installing Pack file cribl-cisco-asa-cleanup-1.1.15 (1).crbl in Group: Dev-OP: failed to install: ENOENT: no such file or directory, open '/opt/cribl/state/packs/cribl-cisco-asa-cleanup.LtY1yaM.tmp/data/lookups/asa_drops.csv'. what does this error suggest we have already uploaded few which got uploaded. 

​Hi Team,I’m working on an SNMP trap pipeline where:Input event has fields like trap_name and trap_varbind_apSysMgmtTaskSuspend.I have a Lookup table that maps:trap_name → varbindname → Output_attribute_value.After Lookup, I want to create a new field dynamically:Field name = value of Output_attribute_value (e.g., id)Field value = value from the field referenced by varbindname (e.g., trap_varbind_apSysMgmtTaskSuspend).I tried using Eval with:JavaScript[Output_attribute_value] = get(__payload, varbindname)Show more lines…but got Unallowed assignment operator error.Then I tried a Code function: JavaScriptconst targetField = event.Output_attribute_value;const sourceField = event.varbindname; if (targetField && sourceField && event[sourceField]) {event[targetField] = event[sourceField];}Show more linesBut the new field (id) still doesn’t appear in the final JSON.Questions:Is Code function the right approach for dynamic field names?How can I verify Lookup values before Code

Is there a way of directly integrating netskope with cribl using rest api’s without using s3 Buckets for transactional logs

We would like to stream data into RDBMS, but we don’t see the option rdbms destination. How can this be achieved?

HI all  I am trying to create a pipeline where all syslog data will land and i want to filter the events from device i want based on a string in _raw filed like firewall or any other unique string.i have tried _raw.includes(‘Firewall’) or /Firewall/ though when i  check in advanced mode in filter tab it matches the correct event but when i am checking it on a sample log i have built for testing it passes all the events regardless of filter.I know this can be done in routes itself but still would prefer if i could build a pipeline and more function inside it for each sources.  

Hi Team,I am currently working on one POC. I have created a Rest Collector, In the discovery section I have configured Crowdstrike API 1 which returns the list of resource ids. Post that, I am using a format discover results section to read all the resource ids one after the other in JS. These ids are dynamically passed to the query parameter of the next API 2 in the collect section. From API 2 response, I need to fetch an attribute related to device id and pass this attribute in the query parameter of the final API 3 whose response will be sent to the Splunk HEC destination.  I am currently not understanding how can I call this third API because Rest Collector doesn’t have  multiple collect sections and when I moved my data to pipeline to implement a code function to call the API 3, looks like its a limitation, I was not able to call external API from code function and I could not see any other functions in cribl that can support this. Is it possible to chain multiple Rest collectors,

Hi everyone,Does any of you ever tried to use the Logging level  known as silly? I’ve tried to use it for troubleshooting an issues on my env, but after less than 10 minutes, my three worker nodes were experiencing memory issues. One of my nodes went completely down, the other two remained with less than 1 GB of RAM (starting from 9 GB of free space in the beginning). I just want to know your experience/opinion on this, is it possible that my memory was not enough? 

Hello,I’m using Cribl Cloud to pull JSON events from an Azure Event Hub and forward them to Splunk via HEC. Each incoming event contains a nested array field called records, for example:{ "records": [ { "FileName": "xx", "FileType": "xx", "NetworkMessageId": "xx", "RecipientEmailAddress": "xx", "RecipientObjectId": "xx", "ReportId": "xx", "SHA256": "xx", "SenderDisplayName": "xx", "SenderObjectId": "x", "SenderFromAddress": "x", "FileSize": x, "Timestamp": "xx", "TimeGenerated": "xx", "_ItemId": "xx", "TenantId": "xx", "_TimeReceived": "xx", "_Internal_WorkspaceResourceId": "xx", "Type": "xx" }, { "FileName": "xx", "FileType": "xx", "NetworkMessageId": "xx", "RecipientEmailAddress": "xx", "RecipientObjectId": "xx", "ReportId": "xx", "SHA256": "xx", "SenderDisplayName": "xx", "SenderObjectId": "x", "SenderFromAddress": "x", "Fil

HI all just wanted to confirm if CIDR ranges are supported in no proxy setting where i want to mention CIDR range of leader node in worker node settings instead of directly providing leader node IP.Is there any additional settings needed to make this work? 

As the title says, I’m looking to create and update a lookup table based on incoming events, somewhat similar to the outputlookup function in splunk. Is there any way to update or create a table based on fields from events passing through a pipeline?

Looking for a configuration example for sending webhook notifications to Teams channel.

hello,i need options on how to enrich data coming from zabbix as a source on cribl stream before it reaches the destination by API or Http requestthe data is on database i need to call the database by API to fetch the data using fields in the data payload from zabbix and enrich the data received from zabbix then forward it to destinationnote : i want to get the data on fly and the API call will use attributed from the data payload this is the URL that i want to use and will take the massagegroup and the application value from the data payload to call the needed data to be enrichedhttp://IP:25050/3i_service.php?MESSAGEGROUP=X&APPLIKATION=Yi tried by code on the pipeline to do httprequest but it didn't work

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?

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

HiI setup a worker node on premise by running the script captured from cribl leader cloud. I enabled UI access for worker node. I can open the link in browser but what will be the credentials for it ?Thanks

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

I am new to cribl and trying to setup Splunk HEC destination from cribl sanbox stream instance. I have provisioned a free splunk cloud instance and setup HEC.

I am trying to pull in DNS Logs from Cisco Umbrella. I have my S3 Connector configured to pull down the logs every 5 minutes. The problem is that it pulls down all the logs. I only want the new logs. I have tried adding the follow to my Conf section of the JSON configuration but it doesn't appear to work."trackProgress": true,      "trackMode": "file",      "trackField": "s3.object.etag",      "useLastModifiedTime": true

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

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.

Hi everyoneI have different locations which need to have separate cribl stream installed on each location .. Which means standalone deployment. In this case how the license will be deployed .. Will it have separate enterprise license applied to each Cribl instance ?

I have installed cribl standalone on a VM , but need to change it to leader ..Do I need a worker node or only a leader can do the processing work as a stream ?If worker node is required, can the same VM be a leader and worked node together ?

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.

Hi,Is there a way to find out which worker node processed an event, does it inject a field or can we configure it?Reason is we have some issues and this could narrow it down to a particular worker node.Cheers,Jay
