Ignite-Visor with Alert and Logs

[Swetad90 <sw...@gmail.com>]

Hi

I am trying to monitor Ignite cluster using the Visor console.

Read the ignite docs and was implementing the below steps -
1. Set up an Alert on the number of nodes/CPUs/CPU usage on a cluster
2.If Alert is met, I am trying to execute a script that will run the visor
in batch mode and display the topology. 

Alert is getting successfully registered. But when I try to write them to a
log file by giving log -l -f="/tmp/visor-log", I am getting below error:
class org.apache.ignite.IgniteException: Failed to query events because
default no-op event storage SPI is used. Consider configuring
MemoryEventStorageSpi or another EventStorageSpi implementation via
IgniteConfiguration.setEventStorageSpi() configuration property.

Went through the below ticket where this is expected:
https://issues.apache.org/jira/browse/IGNITE-4812

1. Can anyone give more idea as to why EventStorageSpi is needed to
configure Alerts?
2. Also, this is happening only when I write the alerts to a log file, is
there any other way to display the alerts other than writing to a file?

I am using ignite 2.0.

Hello @Swetad90

Log command can not collect events when event storage is disabled. I create
separated issue. You can track it by link
https://issues.apache.org/jira/browse/IGNITE-5228

You can execute custom script on alert. See -s flag of alert command.
