Hello Aneesh,

While this doesn't provide a GUI, tablesnap is a community tool that does a
great job at handling backups:

Re: Cassandra Monitoring tool

[Joaquin Casares]

Hello Aneesh,

Alain and I also worked on this project that you might find useful:

https://github.com/thelastpickle/docker-cassandra-bootstrap


It is a Docker Compose environment to showcase the Prometheus graphs that
we worked on. There's still a missing update, so do please check back soon,
but the majority of what we've worked on is housed in that repo. If you
decide to move forward with Prometheus, you can use the curl scripts
provided in the repo to upload the charts and all preset alerts into your
Grafana environment. If you use the GUI to upload the graphs, you'll lose
all preset visual thresholds and alerts, but still keep all completed
tooltips/descriptions.

Now that I remembered it was missing an update, we should push the new
features out sooner rather than later. The new update includes better
descriptive text, alert text, and alert fixes.

Hope it helps!

Re: Cassandra Monitoring tool

[Alain RODRIGUEZ]

Hello,

With more details on your criteria, it would be easier.

I used:

- SPM from Sematext (Commercial - dashboards out of the box)
- Datastax OpsCenter (Commercial, With DSE only nowadays)
- Grafana/Graphite or Prometheus (Open source - 'do it yourself' - but some
templates exist)
- Datadog (Commercial - dashboards out of the box)

It depends what you want really. All those worked for me at some point in
time :).

Note: We built the Dashboards that are out of the box for Datadog. I
believe it should put anyone starting with Cassandra in good conditions to
operate and troubleshot Apache Cassandra. My opinion here is biased most
definitely :). I liked the interfaces of Datadog (using regularly) and
Sematext (old experience) the most.

C*heers,

Thank you Hari for the details.

One more question, please suggest me some cluster managing too for
Cassandra cluster. Looking for opensource tools that will support to take
snapshot and restore via GUI.

Re: EXT: Cassandra Monitoring tool

[Harikrishnan Pillai]

I assume you are using open source cassandra and you can look at Prometheus 
grafana for cassandra monitoring and lot information available in internet 
regarding how to setup the Prometheus monitoring for cassandra .

Cassandra Monitoring tool

[ANEESH KUMAR K.M]

Please suggest me some good cluster monitoring tool for cassandra multi
region cluster.

Cassandra monitoring tool

[Héctor Izquierdo Seliva]

Hi everyone.

Looking for ways to monitor cassandra with zabbix I could not found
anything that was really usable, till I found mention of a nice class by
smeet. I have based my modification upon his work and now I give it back
to the community.

Here's the project url:

http://code.google.com/p/simple-cassandra-monitoring/

It allows to get statistics for any Keyspace/ColumnFamily you want. To
start it just build the jar, and launch it using as classpath your
cassandra installation lib folder.

The first parameter is the node host name. The second parameter is a
comma separated list of KS:CF values. For example:

java -cp blablabla localhost ks1:cf1,ks1:cf2.

Then point curl to http://localhost:9090/ks1/cf1 and some basic stats
will be displayed.

You can also point to http://localhost:9090/nodeinfo to get some info
about the server.

If you have any suggestion or improvement you would like to see, please
contact me and I will be glad to work on it. Right now it's a bit rough,
but it gets the job done.

Thanks for your time!

Hi Ali. You should run it like this

java -cp /home/ali/apache-cassandra-0.6.3/lib/*
com.google.code.scm.CassandraMonitoring localhost ks1:cf1,ks2:cf2,etc

I forgot to mention it has been coded against 0.7.x, and I'm not sure it
will work on 0.6.x. I'll try to add support for both 0.6.x and the new
0.8.x version as soon as possible.
