Hi Team,
We got an requirement to ingest NSG logs from Azure into Splunk Cloud. So we have installed the "Splunk Add-on for Microsoft Cloud Services" in our Heavy Forwarder server and we have created the inputs in Azure Storage Blob and post which I can able to see the logs were getting ingested into Splunk Cloud but a single event seems to be a combination of multiple events.
So I have tried this solution by applying the props and transforms.conf as mentioned below:
https://www.splunk.com/blog/2017/02/20/splunking-microsoft-azure-network-watcher-data.html
props.conf:
[sourcetype]
LINE_BREAKER = }([\r\n]s*,[\r\n]s*){
SEDCMD-remove_header = s/{\s*\"records\"\:s*[\s*//g
SEDCMD-remove_footer = s/][\r\n]\s*}.*//g
SHOULD_LINEMERGE = false
KV_MODE = json
TIME_PREFIX = time\":\"
REPORT-tuples = extract_tuple
transforms.conf:
[extract_tuple]
SOURCE_KEY = properties.flows{}.flows{}.flowTuples{}
DELIMS = ","
FIELDS = time,src_ip,dst_ip,src_port,dst_port,protocol,traffic_flow,traffic_result
Then I have tried the Splunk answers Regex provided in the following weburl:
https://answers.splunk.com/answers/714696/process-json-azure-nsg-flow-log-tuples.html
props.conf:
[sourcetype]
LINE_BREAKER = (\")\d{10}
SHOULD_LINEMERGE = false
SEDCMD-remove_not_epoch = s/\"\D.*$//g
transforms.conf:
[extract_tuple]
DELIMS = ","
FIELDS = time,src_ip,dest_ip,src_port,dest_port,transport,traffic_flow,traffic_result
But still the logs are getting generated as a very big event and after 10000 characters its getting categorized as a single event so kindly help to provide relevant props and transforms.conf so that I can implement in my environment and check the feasibility of it.
can anyone help on the request.
Hi Anand,
Can you please provide any sample log to test regex?
Regards,
Tejas
As requested a single event looks like as below.
