We have installed version 3 of the MEM and Agent. On each monitored server the agent is connected to the local MySQL database. However, when we try to connect to an agent from the MEM UI it fails and enters the following in the agent's mysql-monitor-agent.log:

2014-07-10 18:37:59,679 ERROR com.mysql.etools.agent.transport.http.HttpPollingJobFetcher: Unable to de-serialize agent orders from https://x.x.x.x:18443/v3/Agent/aabd1936-61b3-4e98-abef-587f06676926/orders

Any idea what the problems is?

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...

Please Help!!!

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.

Thanks in advance.

Hi everyone,

Is anyone here familiar with MONyog monitoring tool?

As a DBA, I've been looking for an advanced (and yet simple) MySQL monitoring tool which mainly focuses on detecting performance issues.
I ran into MONyog and tried the trial version. So far it seems pretty neat IMO..

We only have MySQL community servers so using MySQL Enterprise Monitor is irrelevant.

What do you guys think?
Can you recommend about other tools as well?

Thanks in advance,
Rotem

Hi Team,

I wanted to be clear on what ports are needs to be open for MySQL Enterprise server and Agent to communicate.

Can someone clearly fill up the table below.

Source Destination Port
MEM Server Agent server
Agent server MEM server

my understanding is, 18443 is the main port for communication and needs to be open at both the ends( MEM and agent ). Please correct me if I'm wrong.


Thanks,

Duplicate hostid from Agent (2 replies)

How do you make a correction when an agent wants to setup a new server with the same hostid with an existing server? The existing server is the monitor server. The version I am using is 3.0.3. This also occurred in previous versions.

When we were using 3.0.2 I tried to change the hostid in the inventory table and in the configuration file for the agent. Neither seemed to work.
