Hi there,
Is it possible to use a keystore to store this password. I don't want to have any plain text passwords in config file
I'm specifically talking about this setting
xpack.monitoring.elasticsearch.username: "logstash_system"
xpack.monitoring.elasticsearch.password: "changeme"
I made a thread about this but no one replied 
Thanks
I think you just create another keystore entry,
bin/logstash-keystore add X_PWD
Then refer to it xpack.monitoring.elasticsearch.password: ${X_PWD}
Hi rugenl
For some reason it's still not working
/usr/share/logstash/bin/logstash-keystore --path.settings /etc/logstash list
es_pwd
x_pwd
Soon as I change from
xpack.monitoring.elasticsearch.password: "pass"
to
xpack.monitoring.elasticsearch.password: ${X_PWD}
logstash refuses to start

Soon as i change it back to plain text password it starts fine 
The list has lower case, did you add X_PWD or x_pwd? Try using ${x_pwd} in the kibana.yml.
The keystore-doc is confusing, it appears to say that you can only use that exact keyword, but other examples use other keywords, so I think you can add arbitrary keys.
I added X_PWD
What's strange is when I run the list command I get an error
/usr/share/logstash/bin/logstash-keystore --path.settings /etc/logstash list
[ERROR] 2019-08-25 13:27:20.827 [main] secretstorecli - Found a file at /etc/logstash/logstash.keystore, but it is not a valid Logstash keystore. {:cause=>java.io.IOException: Integrity check failed: java.io.IOException: getSecretKey failed: Password is not ASCII, :backtrace=>["org.logstash.secret.store.backend.JavaKeyStore.load(org/logstash/secret/store/backend/JavaKeyStore.java:268)", "org.logstash.secret.store.backend.JavaKeyStore.load(org/logstash/secret/store/backend/JavaKeyStore.java:40)", "org.logstash.secret.store.SecretStoreFactory.doIt(org/logstash/secret/store/SecretStoreFactory.java:109)", "org.logstash.secret.store.SecretStoreFactory.load(org/logstash/secret/store/SecretStoreFactory.java:95)", "org.logstash.secret.cli.SecretStoreCli.command(org/logstash/secret/cli/SecretStoreCli.java:77)", "java.lang.reflect.Method.invoke(java/lang/reflect/Method.java:498)", "org.jruby.javasupport.JavaMethod.invokeDirectWithExceptionHandling(org/jruby/javasupport/JavaMethod.java:425)", "org.jruby.javasupport.JavaMethod.invokeDirect(org/jruby/javasupport/JavaMethod.java:292)", "RUBY.<class:SecretStoreCli>(/usr/share/logstash/lib/secretstore/cli.rb:35)", "RUBY.<main>(/usr/share/logstash/lib/secretstore/cli.rb:16)", "org.jruby.Ruby.runInterpreter(org/jruby/Ruby.java:891)", "org.jruby.Ruby.runInterpreter(org/jruby/Ruby.java:895)", "org.jruby.Ruby.runNormally(org/jruby/Ruby.java:784)", "org.jruby.Ruby.runNormally(org/jruby/Ruby.java:797)", "org.jruby.Ruby.runFromMain(org/jruby/Ruby.java:609)", "org.jruby.Main.doRunFromMain(org/jruby/Main.java:415)", "org.jruby.Main.internalRun(org/jruby/Main.java:307)", "org.jruby.Main.run(org/jruby/Main.java:234)", "org.jruby.Main.main(org/jruby/Main.java:206)"]}
So I recreated everything
set +o history
export LOGSTASH_KEYSTORE_PASS=mypassword
set -o history

I also tried adding the x_pwd to the keystore and setting

Same thing
Thanks for your help
Hello @VamPikmin,
try this :
bin/logstash-keystore add xpack.monitoring.elasticsearch.password
and then enter your password word.
NB : you can comment/delete this line in the .yml
Mehdi.
Hi @mbelaloui
Thanks for your help
I've added it to the keystore but still get 401
/usr/share/logstash/bin/logstash-keystore list --path.settings /etc/logstash
es_pwd
x_pwd
xpack.monitoring.elasticsearch.password
Just want to confirm you want me to comment out the pass from the logstash.yml like this:
xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: logstash_system
#xpack.monitoring.elasticsearch.password: mytextpass
xpack.monitoring.elasticsearch.hosts: ["https://localhost:9200"]
xpack.monitoring.elasticsearch.ssl.certificate_authority: /etc/logstash/certs/ca.pem
In Kibana it was easy
sudo -u kibana /usr/share/kibana/bin/kibana-keystore add elasticsearch.password
kibana.yml
elasticsearch.username: "kibana"
elasticsearch.password: "elasticsearch.password"Hi @VamPikmin
Did it work before adding the keystore rule ???
If no, i think that your user dos'nt have the right to monitore data, to do so you have to add the monitoring rols to your logstash_system.
If not it certainly came from the https, you don't use the right Ca or the user that run logstash dosn't have the correct access right to read it.
Happy to help you Mehdi.
Hi @mbelaloui
It works with the logstash_system user and plain text password in config, that should mean that the user has the right access I would imagine?
Thank you 
Does it work for you in kibana ?
I just tryed it with kibana, elasticsearch and logstash 7.2.0 and it's ok for me.
My logstash config:
cat config/logstash.yml | grep "^[^#]"
xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: "Remote_beats"
xpack.monitoring.elasticsearch.hosts: ["elasticsearch-node-1:9200", "elasticsearch-node-2:9200"]
xpack.monitoring.elasticsearch.ssl.certificate_authority: "/home/elastic-user/logstash/ca.crt"

in Kibana-keystor
sudo /usr/share/kibana/bin/kibana-keystore --allow-root list

then, it's ok when i try this :
bin/logstash -e 'input { stdin { } } output { stdout {} }
and also i'am seeing the logstash in the monitoring kibana interface.
NB: when you add your password to the keystore be sure that you set your password correctly and without the <"">.
Mehdi.
Kibana is fine
This is what my config looks like:
cat /etc/kibana/kibana.yml | grep ^[^#]
server.host: "localhost"
elasticsearch.hosts: ["https://localhost:9200"]
elasticsearch.username: "kibana"
elasticsearch.password: "elasticsearch.password"
server.ssl.enabled: true
server.ssl.certificate: /etc/kibana/certs/instance.crt
server.ssl.key: /etc/kibana/certs/instance.key
elasticsearch.ssl.certificate: /etc/kibana/certs/instance.crt
elasticsearch.ssl.key: /etc/kibana/certs/instance.key
elasticsearch.ssl.certificateAuthorities: /etc/kibana/certs/ca.pem
elasticsearch.ssl.verificationMode: certificate
Since then I also added this to the kibana config to match yours
xpack.monitoring.enabled: true
xpack.security.enabled: true
This is all I have in kibana keystore as shown before
/usr/share/kibana/bin/kibana-keystore --allow-root list
elasticsearch.password
My logstash.yml
cat /etc/logstash/logstash.yml | grep ^[^#]

xpack.monitoring.elasticsearch.ssl.certificate_authority: /etc/logstash/certs/ca.pem
I always get this error when I run logstash-keystore but not trying to worry about that now

And tell me if it's works.
Very happy to help !!!

There is nothing I can find in the documentation that allows to use a keystore instead of a plain text password
EDIT:
There seems to be an issue with this line in logstash.yml
xpack.monitoring.elasticsearch.hosts: ["https://localhost:9200"]
I've tried using 127.0.0.1, no joy
If I change to 0.0.0.0 I get a certificate error, so I would need to regenerate them I guess

I think that logstash can work without java, but keystore no
Hi @mbelaloui

You say it's working for you with just the username-
xpack.monitoring.elasticsearch.username: "Remote_beats"
Maybe I should change to using network ip instead of localhost and see whether that works
EDIT: Nope

Well, in the end it was an issue with the ES_PWD. I exported it as root logstash runs under the logstash account and I can't su to logstash to export it under the right account
I added LOGSTASH_KEYSTORE_PASS to
cat /etc/default/logstash
LS_HOME="/usr/share/logstash"
LS_SETTINGS_DIR="/etc/logstash"
LS_PIDFILE="/var/run/logstash.pid"
LS_USER="logstash"
LS_GROUP="logstash"
LS_GC_LOG_FILE="/var/log/logstash/gc.log"
LS_OPEN_FILES="16384"
LS_NICE="19"
SERVICE_NAME="logstash"
SERVICE_DESCRIPTION="logstash"
LOGSTASH_KEYSTORE_PASS="myplaintextpass"
After that I was able to use anything from the keystore as the password
/usr/share/logstash/bin/logstash-keystore --path.settings /etc/logstash/ list
elasticsearch.password
es_pwd
xpack.monitoring.elasticsearch.password
So either of these will work:
xpack.monitoring.elasticsearch.password: "${ES_PWD}"
xpack.monitoring.elasticsearch.password: "${elasticsearch.password}"
xpack.monitoring.elasticsearch.password: "${xpack.monitoring.elasticsearch.password}"
The ES_PWD variable will also work in logstash.output.elasticsearch which is great
Thanks for all your help @mbelaloui and @rugenl
