Seyren not picking up alerts from graphite

[siva-sfly]

Hi,

We've a graphite server with seyren installed on the same server. I recently moved seyren to a different server (exported mongodb data from the old server and imported into the new server). After I start seyren, I only see the alerts from the migrated data. I don't see any new alerts? Any idea how to fix it?

Thanks,
Siva

do you see anything in the log?

Here's a gist of the seyren.log on startup https://gist.github.com/siva-sfly/f483224345a9326835219a53268fb810. I see connections made to mongodb but not to graphite initially. After a long time when a check tried to run, I see some graphite connection errors.

I tried making a sample connection to graphite using SSLPoke. Here's the error. Do I need some kind of ssl certs to make this work?

@alenkacz Any idea how to fix the error I posted in the previous comment?

[alenkacz]

@siva-sfly your graphite runs on https? because the ssl manager is used only for graphite on ssl. Can you post also snippet with how seyren is started (the config)

[siva-sfly]

@alenkacz Yes, our graphite runs on https. Here's the seyren startup config.

GRAPHITE_URL="https://graphite.domain"
export GRAPHITE_URL

MONGO_URL="mongodb://localhost:27017/seyren"
export MONGO_URL

GRAPHITE_USERNAME="graphite_user"
export GRAPHITE_USERNAME

GRAPHITE_PASSWORD='graphite_pass'
export GRAPHITE_PASSWORD

SEYREN_URL="http://localhost:8080/seyren"
export SEYREN_URL

SEYREN_LOG_PATH="/var/log/seyren/"
export SEYREN_LOG_PATH

PIDFILE='/var/run/seyren/seyren.pid'
CHECK_PID_RUNNING=$(ps -ef | grep seyren | grep -v grep | awk '{print $2}')

USER=seyren
GROUP=seyren


start-stop-daemon --start --make-pidfile --chuid seyren --pidfile /var/run/seyren/seyren.pid --exec /usr/bin/java -- -jar /opt/seyren/seyren-web-1.4.0.jar -extractDirectory /opt/seyren/.extract

@alenkacz Any new ideas based on my previous comments? We're still not able to get this working.

This can probably be closed out. The problem was indeed due to SSL certs. I created a keystore, added in the proper certs that matched with the domain that Seyren was supposed to communicate with, and then passed in the keystore via jvm options.

java -jar /opt/seyren/seyren-1.5.0.jar -Djavax.net.ssl.trustStore=/opt/seyren/ssl/clientkeystore -Djavax.net.ssl.trustStorePassword=superdupersecret

Once that was done, it took a while for Seyren to 'catch up' since there was a lot of old data in mongo.

For anyone coming across this thread, here are the rough steps for making Seyren SSH friendly:

keytool -keystore clientkeystore -genkey -alias client
keytool -import -keystore clientkeystore -file yourservercert.cert -alias yourserverdomain

Then include the path to the store either with environment variables or, like above, jvm options.
