Subscribe to LEAFNODE.CONNECT and LEAFNODE.DISCONNECT events

[ZarkoRunjevac]

Hi, I am trying to subscribe to LEAFNODE.CONNECT and LEAFNODE.DISCONNECT events. My hub is configured as

jetstream {
    store_dir: "/data"
    domain=hub
    max_memory_store: 8GB
    max_file_store: 1TB
}
accounts: {
    SYS: {
        users: [
            { 
                user: "admin", 
                password: "changeit"
            }
        ]
    }
}
system_account: SYS
leafnodes {
    port: 7422
}
port: 4222
http_port: 8222

and leaf node is configured as

jetstream {
    store_dir: "/data1"
    domain=leaf1
}
port: 4333
leafnodes {
    remotes [
        {
            urls: ["nats://nats-main:7422"]
        }
    ]
}

When I subscribe to events on hubusing command:

 nats -s localhost:4222 sub '$SYS.>' --user admin --password changeit

I never receive LEAFNODE.CONNECT and LEAFNODE.DISCONNECT events.
Do I need to setup anything else in order to receive these events?

From the system account you can subscribe to the following.

$SYS.ACCOUNT.*.CONNECT

This will show all connections of all types for all accounts. The third token is the account.

e.g.

[#1] Received on "$SYS.ACCOUNT.ADEREKYKHPGHKP3UOOWSTAVFTYSFSXZELVLTRXOWQ74RG7CI2BFUKOQ3.CONNECT"
{"type":"io.nats.server.advisory.v1.client_connect","id":"jf9HGwRRs9OWS65PwUxOVc","timestamp":"2024-09-18T21:28:49.735218109Z","server":{"name":"aws-uswest2-natscj1-3","host":"52.26.44.194","id":"NCYS3GAN7R5FEPE5AZSRMGLLMXV7MTIFI4UDCEACTQHHP4NBRHYI5A3I","cluster":"ngsprod-aws-uswest2","domain":"ngs","ver":"2.10.21-RC.1","tags":["cloud:aws","cluster:ngsprod-aws-uswest2","country:us","geo:us","geo:us-west","index:3","instance:aws-uswest2-natscj1-3","pool:natscj1","region:uswest2","stack:ngsprod","zone:uswest2c"],"jetstream":true,"flags":3,"seq":546495,"time":"2024-09-18T21:28:49.735390986Z"},"client":{"start":"2024-09-18T21:28:49.566571361Z","host":"76.91.2.75","id":82322,"acc":"ADEREKYKHPGHKP3UOOWSTAVFTYSFSXZELVLTRXOWQ74RG7CI2BFUKOQ3","user":"UDFQRH4SMFSFFR5CQUYSQQXZQZ3RUPUGCRQZ5KHACCPTSTVQTXQKFEDW","name":"ngs-leaf-derek","ver":"2.11.0-dev","jwt":"ey...","issuer_key":"ADEREKYKHPGHKP3UOOWSTAVFTYSFSXZELVLTRXOWQ74RG7CI2BFUKOQ3","name_tag":"derek","kind":"Leafnode"}}

If you want only the leafnodes, you can subscribe to the following, again from the system account.

$SYS.ACCOUNT.*.LEAFNODE.>

e.g.

[#1] Received on "$SYS.ACCOUNT.ADEREKYKHPGHKP3UOOWSTAVFTYSFSXZELVLTRXOWQ74RG7CI2BFUKOQ3.LEAFNODE.CONNECT"
{"server":{"name":"aws-uswest2-natscj1-4","host":"44.235.52.92","id":"NBDVJN5SI4SN62JKEHFG3PLDOJ6YD4NJ5QI7477ESGXEGNA6NIYF5OEV","cluster":"ngsprod-aws-uswest2","domain":"ngs","ver":"2.10.21-RC.1","tags":["cloud:aws","cluster:ngsprod-aws-uswest2","country:us","geo:us","geo:us-west","index:4","instance:aws-uswest2-natscj1-4","pool:natscj1","region:uswest2","stack:ngsprod","zone:uswest2a"],"jetstream":true,"flags":3,"seq":534314,"time":"2024-09-18T21:26:26.622509189Z"},"acc":"ADEREKYKHPGHKP3UOOWSTAVFTYSFSXZELVLTRXOWQ74RG7CI2BFUKOQ3"}
