Description


Hello I'm trying to setup alarms on Pinpoint but when i follow the guide in this link i'm not able to do because i got an error Message:
https://github.com/naver/pinpoint/blob/master/doc/alarm.md

captura

captura2

Error Message says:Exception occurred while trying to CRUD user information

I'm searching in this repository for any post related i found the following links:
1- https://github.com/naver/pinpoint/issues/2857 This has as a response a link to https://github.com/naver/pinpoint/blob/master/doc/alarm.md

2- https://github.com/naver/pinpoint/issues/3355 This isn't clear, says something about "out of the box"

3- https://github.com/naver/pinpoint/issues/3444 This says something about a DB, i don't really understand what DB it refers. =(

4- https://github.com/naver/pinpoint/issues/1878 This says something about "implement the necessary classes, and build from source"

May be is more related Issues but i dont really understand if is necesary to develop something around this problem (ie to write some code to have this feature) because in some of the links that i have mentioned i read about "implement". If is necesary to develop some code i really apreciatte a guide about that or some information that help me to solve this problem.

Thanks in advance. =D

Environment

  • Pinpoint version: 1.8.0 SNAPSHOT
  • OS, WAS, affected library, etc: Ubuntu Server 16.04

First of all, you have to install and configure correctly our MySQL Server. You must create a pinpoint database and the respective tables (Scripts are in the installation page of GitHub).
Second, make sure hour credentials are correct. For example, the datasource configuration file is in pinpoint-web war file. It is placed in WEB-INF/classes/jdbc.properties.
There, you can see the credentials like this:
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:13306/pinpoint?characterEncoding=UTF-8
jdbc.username=admin
jdbc.password=admin
Note that the port is not the MySQL default port. You must change it to 3306.
Hope it is useful.

Hi @ing-arriola

Hi @minwoo-jung

Sorry I had not been able to answer

I do not know where the Log file that you comment is located ... I suppose it should be in the WAS where I have deployed Pinpoint, which is a Tomcat, I hope you can comment on where I can find the Log file to share it here.

Beforehand thank you very much

@ing-arriola
you should find log file in tomcat log folder where execute pinpoint-web.

Hi @christianorios
Wow!!
I completely ignored that an additional database should be installed so that this feature could be used ..... I had also previously asked if for this feature to be used it is necessary to write some lines of code...but I had I understood that it was not like that !! ... I was reviewing the documentation that can be accessed from the following link:
https://github.com/naver/pinpoint/blob/master/doc/alarm.md

In the aforementioned link this is mentioned:
c1

But when I checked the file on the source that was cited on the route com.navercorp.pinpoint.web.alarm.AlarmMessageSender , what I found was this:

c2
From there I had previously thought that I should develop the logic to send an SMS or to send an email. I would be very helpful in confirming my suspicions or also confirming that I am wrong.

Beforehand thank you very much.

Hi @minwoo-jung
In response to your comment I share the link of the TOMCAT Log.

I did my best to share only the parts of the Log that show the error but I currently have some limitations in my computer, so I have put the complete Log that has a size of around 2GB, it is practically a month of Log that I share. The days that this problem happened to me were 2018/4/26 in the morning between 9:00 am and 11:00 am. Also the day 2018/5/02 between 8:00 am and 10:30 am.
[FILE DELETED]

Beforehand thank you very much.

You should find exception messge yourself when called CRUD api.

I will review the file that I had previously published and only publish the Log lines where the error and the environment that is considered convenient around them is observed.
