Hello team,

i have installed elastiflow with elasticsearch, kibana, and flow collector. after compose up command snmp-collector keeps restarting. i have basic license error below.

tried to create .env file and store id and license key

{“level”:“info”,“ts”:“2026-02-22T15:38:56.170Z”,“logger”:“snmpcoll.license.license[default]”,“caller”:“envconf/logger.go:49”,“msg”:“EF_SNMP_LICENSED_CORES=0”}
{“level”:“fatal”,“ts”:“2026-02-22T15:38:56.171Z”,“logger”:“snmpcoll”,“caller”:“snmpcoll/main.go:64”,“msg”:“exiting because of a license error”,“code”:“license/error”,“reason”:“failed to create license: failed to parse license key: signature is invalid”,“stacktrace”:“main.main\n\t/app/cmd/snmpcoll/main.go:64\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:271”}

if is use the id and license in docker yaml getting below error. license key is so big

msg":“EF_SNMP_LICENSED_CORES=0”} {“level”:“fatal”,“ts”:“2026-02-22T14:10:47.315Z”,“logger”:“snmpcoll”,“caller”:“snmpcoll/main.go:64”,“msg”:“exiting because of a license error”,“code”:“license/error”,“reason”:“failed to create license: failed to parse license key: illegal base64 data at input byte 0”,“stacktrace”:“main.main\n\t/app/cmd/snmpcoll/main.go:64\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:271”}

It seems like the key you are using is invalid? If you want to message me your license information, I can test it. Here is what my license entry looks like in my (natively installed) SNMP collector looks like.

snmpcoll-license

You are using version 7.6.0 of the collectors. That is when the licensing paramaters changed. See this note in the Changelog:

EF_FLOW_LICENSE_KEY and EF_SNMP_LICENSE_KEY are no longer used. It is simply EF_LICENSE_KEY and you should be able to use the same license key for both collectors.

Note that the latest version is 7.21.0.
