    I don't see anything in the release notes to suggest it will help, but there is a new version of the jmx_exporter

    I missed this at the time...or had forgotten: "On 30 November 2018, complying with the Code of Conduct, Jarkko Sakkinen of Intel sent out patches replacing instances of "fuck" appearing in source code comments with suitable versions focused on the word 'hug'."

    The Thursday useless meeting.

    "Ok, we need to do this"

    "ok, I'm mark it as failed"

    WTF is even happening.

    it's the official repo:

    [root@localhost lib]# yum repolist
    Last metadata expiration check: 0:00:14 ago on Wed 13 May 2020 08:38:52 PM CDT.
    repo id repo name status

    zabbix Zabbix Official Repository - x86_64 18
    zabbix-non-supported Zabbix Official Repository non-supported - x86_64 1

    I guess Prometheus is pretty popular, but I suspect this is a problem with the prometheus agent and not Cassandra.

    I was able to unjar the file and then in the manifest I noticed it pointed to a different file for classpath.

    same issue with that file though

    [root@localhost lib]# java -javaagent:./jmx_prometheus_javaagent-0.12.0.jar=8080:jmx-prom.yaml -jar /usr/share/cassandra/apache-cassandra-thrift-3.11.6.jar -Djava.util.logging.config.file=./program.log
    no main manifest attribute, in /usr/share/cassandra/apache-cassandra-thrift-3.11.6.jar

    It seems unlikely to me that something like #Cassandra would be missing such a file. Do I need to build Cassie from source to get this or something? I haven't been able to find anything to suggest this is a common issue. Is it lying and the javaagent is actually the issue? #java

    [root@localhost tmp]# java -javaagent:./jmx_prometheus_javaagent-0.12.0.jar=8080:jmx-prom.yaml -jar /usr/share/cassandra/apache-cassandra-3.11.6.jar -Djava.util.logging.config.file=./program.log

    my suspicion, after reading https://stackoverflow.com/questions/26573940/why-cant-create-a-new-user-in-mysql is that zabbix had me import the user in an earlier step so that the user existed.

    Which gets me back to the original statement...that the zabbix instructions could use some work

    The weird thing is that the CREATE statement worked. This may be because of the hostname, but I got it working, so I am no longer worried about it.

    the error specifically says you cannot use GRANT to create user. Maybe you could in earlier versions of MySQL? You can't in MySQL 8.whateverIhave

    Hmm, it probably is true: "Please note that the interfact to the JMX uses a small jar file contained in this module, so you will need to have java installed on the machine you're running this module on." https://pypi.org/project/jmxquery/

    noticing a lot of typos in the things I am copying and pasting...

    "Why the exporter is not written in GO ?

    Cassandra metrics are only available trought JMX, which in turn is only accessible with Java."

    The Go question is a bit eye-rolly, but I wonder if the answer is actually true.

    my experience is limited, but SPD seems a lot easier that Look. Look is what we have on our Peloton.

    The whole "clip" terminology is really weird since they call being clipped-in "clipless". I believe the clip must refer to something very specific and historical.

    I have nagios, Prometheus, and Zabbix all installed. I am ready to be the !monitoring guy!

    At some point, I need to set up the #ElasticStack, #FluentD, and #Grafana, but Grafana in particular I don't see as a monitoring tool. It is a visualization tool. It is often in the stack with Prometheus, and I need to know it, but I don't see it as a priority. The priority is to get Prometheus monitoring my #Cassandra install.

    for example, need to create a user before this grant command:

    # mysql -uroot -p
    password
    mysql> create database zabbix character set utf8 collate utf8_bin;
    mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'password';

    so, the exam didn't go into any of the AKS, EKS, and GKE stuff...so that's good to know. Apparently, I'm proficient, which is nuts. I'm only 34% through the videos, so I guess I will keep on trucking to get that expert badge
