MEM customizing and bugs?! (3 replies)

Hello everyone,

I'm using MySQL Enterprise Monitor 3.0.5. Is there any possibility to customize the dashboard, eg. one database activity graph for every instance?
Does anyone know this?


Second, I have 2 bugs on the dashboard:
After an auto-refresh the 'Connections - All MySQL-Instances' diagram changes from stacked to line.
After a login or an auto-refresh the colors of the 'Database Activity - All MySQL Instances' diagram changes.
For rechanging the diagram, I have to move the mouse or I have to toggle the diagram type.

before-refresh-picture: http://www.directupload.net/file/d/3516/nnctaryi_png.htm
after-refresh-picuture: http://www.directupload.net/file/d/3516/nj2qtqqj_png.htm


At the query-analyzer, detailed, graph-tab, there is no graph viewable.
Is this a bug or a feature?

Hoping for help :)

problem working with mysql monitor dashboard (3 replies)

Hello to all,

I am new in mysql. I am trying to work with mysql monitor 3.0. Following is the setup that I have used. Please correct me where I am wrong.

I downloaded
mysqlmonitor-3.0.4.2920-linux-x86-installer.bin for service manager and
mysqlmonitoragent-3.0.4.2920-linux-x86-32bit-installer.bin for the agent

./mysqlmonitor-3.0.4.2920-linux-x86-installer.bin

I enterd following values when insatller prompts:

Installtion Directory: /opt/mysql/enterprise/monitor

Tomcat Server port : 18080
Tomcat SSL Port: 18443

Service manager User Account: mysqlmem

database installtion: I wish to use an bundled mysql database.

REpository user name: service_manager
After entering password,

MySQL database port: 13306

Use SSL when connecting to the database box is uncheck.

After Installation, I start the browser to open Enterprise manager's first UI.
https://localhost:18443/Setup.action

Create Manager User: admin
password: ******

Create agent user: agent_user
password: ******

Rest I used all the defaults.

After completing the setup, it shows me that I logged in as admin user.

But he is enable to do anything with the UI. He cannot create group. No mysql instances are being displayed here, no monitored hosts are being

displayed here. I read that mysql monitor 3.0 has now built-in agent. So, according to me there should be some monitored hosts in the UI window.

Query Analyzer Problem loading data (3 replies)

Hello Everyone,

I have a problem with the query analyzer.

If I want, to view the querys of the last days (1d and 2d), the analyzer loads the the data, but will be achieves no result.

When I change the instance or group, this error-message appears: 'Communication Error Cannot load Data'

The data purge behavior is on default value (4 weeks).

While the analyzer tries to load the data, the host of the Monitor-Server has a massive growth of the CPU iowait time (30%-40%).

This problem concerns every mysql-instance.

The asset selection tree on the left-hand side of Enterprise Manager never finishes loading, it just has a spinning icon. Because of this, I can't select the database that I am interested in viewing in the Query Analyzer.

Does anyone have an idea on how to fix this or how to find more details?

Enterpise Monitor is getting the following error when attempting to connect to the instance to be monitored:

JDBC operation against localhost:3306 failed due to Could not get JDBC Connection; nested exception is java.sql.SQLException: Connection was closed in SingleConnectionDataSource. Check that user code checks shouldClose() before closing Connections, or set 'suppressClose' to 'true'. Will not retry (operation was not retry-able or no retries are left)

I have found that the error comes from the "Spring" Java framework, but I have no idea how I am supposed to fix this. Any ideas?

Monitor Agent creates massive slow queries (2 replies)

Hello,

my company analyzes the logfiles of the mysql-server.
There we can see, that the monitor agent creates a lot of entries in the slow query logfile. They are so long, that we can see the full logentry in the slow query as well in the analyzing tool.

Is there a possibility to prevent creating logentries caused by the agent?

Hi

Has anyone managed to get the agent in MySQL EM to deploy on an Amazon RDS instance running MySQL.

The RDS seems quite locked down and one cannot even SSH via Putty onto the box.

Any workarounds ?

MEM Agent starting but not working. (1 reply)

Dear all,

I've got the MEM Service Manager up and running without problems and it's monitoring local instances of Mysql that are on the same box.

However upon installing the Agent on my Ubuntu 12.04 linux boxes I get a number of errors and I wonder if anyone else has come across them and found a workaround. See log file below including numerous stack traces.

I Googled the error message (of course!) and there were zero hits which makes me wonder what might have gone wrong during install, which seemed to be fine. But maybe someone out there has a clue about this...

[I would particularly like to know if the Agent is passing info to the Service Manager via GET/POST/HTTP and if these can be done on the command line.]


Ubuntu 12.04
MEM Service Manager: 3.0.10.2987
Agent: 3.0.11

Any insights? Where do I start looking?

Thanks!

Hi Guys

I am new to MySQL

We have MEM 3.0 (enterprise monitor) in our shop and I am trying to configure email notifications.

I read somewhere were it is indicated that I should go to Settings -> Global Settings and configure the Outgoing Email settings, but when I go to Global Settings I don't have Outgoing Email settings.

I find the email settings under configuration->event handling, is this ok?

I have SMTP server but I don't know the SMTP Server Login and From Address details, is the way to get these information from the server?

Thanks in a advance...

Memory: Correlate prstat with NDB Config values (1 reply)

I need to upgrade the memory of my Solaris MySQL Cluster. I know my NDB Nodes are running low on memory but I can't seem to get a good correlation between `prstat -s rss` and the values in my management server's config.ini file.

The config.ini shows:

SendBufferMemory=4M
ReceiveBufferMemory=4M
DataMemory=5004M
IndexMemory=883M
SharedGlobalMemory=1024M
# DiskPageBufferMemory=2048M
StringMemory=25
TransactionBufferMemory=8M

And when I go on one of my nodes (All 6 report the same total memory of 7781) and run `prstat -s rss` I see the following:

PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
76717 root 7781M 7575M sleep 6 0 785:06:54 1.5% ndbd/40


When I add up the memory in the config file I get 6952M. Why do I not get 7781M?

Can someone please help me find the most accurate correlation of memory between prstat and the config file?

Thanks in advance

MEM - agentless setup (2 replies)

Hi,
I have MEM 3.0 installed on linux box, trying to monitor MySQL 5.6 instancess in an agentless setup.

Based on the docs the Service manager component has built-in agent, so there is no agent installed on that MEM box - and I get events from remote instances

First of all - is that "Service Manager only" install correct for a MEM 3.0 server?

And the second question is (probably) related to the first one. I need to add some custom data collections to my setup to be able to create new/modify existing advisors. The documentation states "add custom.xml to etc folder of agent" ...
How do I add custom data collections to an agentless setup? Is that even possible to have it defined on MEM server and use it for remote monitoring?
When I tried to add custom.xml to /opt/mysql/enterprise/monitor/etc (or event manually created /opt/mysql/enterprise/agent/etc) it's not reflected in the GUI
Thanks

We are using Mysql Enterprise dashboard in our application to monitor CPU Utilization,Database Activity,Connections and Replication.

I used to do some analysis with 1 month data using data downloaded(CSV) from Enterprise dashboard.

I have seen that similar kind of data stored in MEM database, but i like to use sql query to retrieve data instead of CSV download.

Could you please provide SQL query used for CPU Utilization,Database Activity,Connections and Replication CSV download, which will help me to process further.
