Hi, Igniters.
I'm working on cluster profiling and the tool for creating a performance report. [1] I have prepared PoC based on performance logging to a separate category of Ignite log. The report contains: - Cache operations and its distribution by types [2] - Transactions and histogram of durations [3] - SQL and Scan query statistics, top of slowest queries, logical and physical reads by query [4] - Compute statistics, top of slowest tasks and their jobs [5] Soon I will add: - Topology and Ignite versions info - Client ID in case of operations from clients For now, I'm developing a binary logging format to reduce the effect on performance. I'll try to reuse Ignite mechanisms. I would like to hear suggestions for the profiling and the performance report.

Hello, Nikita
Nice to have such a tool in Apache Ignite. Can you provide more information about the binary logging format? Do you have any examples? Is there are any problems you faced? >The Ignite will log some additional internal statistics using separate log category of IgniteLogger. What the additional log category are you talking about?

Hello Nikita,
Perhaps, I am missing something... Apache Ignite already has a web-console tool. Do we want to improve the existing tool instead of creating a new one? It seems to me, this can be confusing for users. - visor (which is deprecated) - web-console (to be honest, I don't quite understand the status of this tool) - new ignite-profiling (which is a monitoring tool as well, judging by the provided link [1] ) I am not against the new tool, I just want to understand the motivation to not improve the existing sub-projects.

Hello!
You need to throw in control.sh also, which does some kind of statistics too, such as idle_verify.

Slava,
The web-console is used to interactive configuration wizard, management and monitoring tool [1]. I want to implement a profiling tool.

Nikita,
Thanks for preparing the IEP and breaking the initiative down into pieces. I studied the IEP and it feels like the goal is to built a tool similar to Oracle AWR. If it's so then shouldn't we add this as an extra function to either visorcmd or control.sh. Hopefully, we can start moving in the direction of the tooling unification. Speaking of the probes/statistics collection approach, is it supposed to reuse tracing capabilities that are to be added as part of IEP-35? [1]. According to the draft of our roadmap [2], @Ivan Rakov <[hidden email]> is planning to contribute to the feature this year.

Hello, Slava, Ilya, Denis.
Thanks for joining this discussion! > - visor (which is deprecated) Who deprecated visor and when? Maybe I miss something? > - web-console (to be honest, I don't quite understand the status of this tool) +1. > I am not against the new tool, I just want to understand the motivation to not improve the existing sub-projects. It's true that, for now, Ignite doesn't have "tool strategy" I think it's a big issue from the user's point of view. We should solve it in the nearest time. Feel free to start this activity. > - new ignite-profiling (which is a monitoring tool as well, judging by the provided link [1] ) The general idea is the following: 1. We should have some profiling mechanism that will generate a node-local event log 2. We should have a tool that can export events to some third-party system. This system can be an Elastic Search(Kibana) or Ignite performance report or Kafka log, whatever. 3. Ignite performance report, in the first release, should be a "static" tool. This means we take static logs(that is not rewritten in the analysis time) and feed them in the script(or tool or control.sh, whatever) The script produces static report that can be used for overall performance analysis. The primary users of this report is a developer of Ignite based applications and performance engineers. Ilya, > You need to throw in control.sh also, which does some kind of statistics too, such as idle_verify. Please, clarify your idea: We should use some info from control.sh to the report? The report should be generated by some control.sh subcommand? Denis, > Speaking of the probes/statistics collection approach, is it supposed to reuse tracing capabilities that are to be added as part of IEP-35? For now, we don't have any results of tracing development available in Apache Ignite. Hopefully, we got some in a couple of weeks. After it, we can start a discussion of how to merge two improvements. > 24 апр. 2020 г., в 20:32, Denis Magda <[hidden email]> написал(а): > >> >> Tracing is more deeply takes statistics.

Hello Nikolay,
> Who deprecated visor and when? Maybe I miss something? On the one hand, there was technically no community consensus that this tool should be obsolete. On the other hand, my opinion based on the following topic: http://apache-ignite-developers.2346864.n4.nabble.com/Re-Visor-plugin-tp44879p44939.html Moreover, it seems to me, currently, the control utility is widely used and actively developed, instead of the visor. > It's true that, for now, Ignite doesn't have "tool strategy" I think it's a big issue from the user's point of view. I absolutely agree with that. > We should solve it in the nearest time. Feel free to start this activity I have no plan at the moment. However, at the first stage, we could understand the difference between visor and control utility. All useful features from visor should be moved/implemented in control utility and after that visor tool and should be marked as deprecated/obsoleted. > You need to throw in control.sh also, which does some kind of statistics too, such as idle_verify. > Please, clarify your idea: > We should use some info from control.sh to the report? > The report should be generated by some control.sh subcommand? If I am not mistaken, the oracle database has AWR tool (mentioned on the IEP page) which is a command-line utility that generates HTML reports. I like this idea and I think this is a good approach that can be realized in the control utility. If we have a case that cannot be implemented in this way, we have to clearly states the difference between these tools so as not to confuse our users. What do you think?

Hi, Igniters.
I have implemented cluster profiling and tool to build the performance report. It's ready to be reviewed. [1, 2] Profiling can be managed by JMX bean. I have plans to implement it to control.sh also. Nodes write statistics to the temporary off heap buffer and then one thread flushes to the profiling files. The write mechanics and format is like WAL logging. The report contains the following statistics: - nodes and caches info - cache operations and transaction statistics - SQL and scan queries statistics (include logical and physical reads per query) - tasks and jobs statistics. More details in the IEP [3]. [1] https://github.com/apache/ignite/pull/7693 [2] https://issues.apache.org/jira/browse/IGNITE-12666 [3] https://cwiki.apache.org/confluence/display/IGNITE/Cluster+performance+profiling+tool вс, 26 апр. 2020 г. в 17:29, Вячеслав Коптилин <[hidden email]>: > > Hello Nikolay, > > > Who deprecated visor and when?

Nikita, Igniters,
I left a few comments on the tool itself in the PR. However, I would like to reiterate and discuss why a user would prefer to use the profiling tool over tracing? Profiling tool only captures very high-level details of the operations (a single cache operation, for example), and does not interconnect operations happened on different nodes. For example, a user would not be able to match a long task with a long job in that task. In other words, profiling data is always a subset of data collected by tracing. Maybe it makes sense to adopt local log file approach to write spans so we can process those spans later to build a report? чт, 4 июн. 2020 г. в 11:16, Nikita Amelchev <[hidden email]>: > Hi, Igniters. > > I have implemented cluster profiling and tool to build the performance > report.

Hello, Alexey.
Thanks for the review. My understanding if the following: We will have 3 in-depth tool to find issues in cluster: 1. Metrics + System views - data that describe Ignite entities very high-level. 2. Profiling - tool to know what specific query of transactions are slow. In many cases, this knowledge is enough to fix the issue(rewrite query, redesign transactions flow, etc) 3. Tracing - tool to know why one of 1000 of the same queries was slow. The most detailed view of the Ignite internal processes. > For example, a user would not be able to match a long task with a long job in that task. This is not true. Profiling report will aggregate data from all nodes. So there will be both * summary time of the task * time of the each job in the task. > 8 июня 2020 г., в 12:52, Alexey Goncharuk <[hidden email]> написал(а): > > Nikita, Igniters, > > I left a few comments on the tool itself in the PR. > > However, I would like to reiterate and discuss why a user would prefer to > use the profiling tool over tracing?

Hello Nikita,
I observed we have an open PR in ignite repo for this feature with different set of changes compared to ignite extensions repo. apache/ignite#7693 <https://github.com/apache/ignite/pull/7693> https://github.com/apache/ignite-extensions/pull/16 Can you please share more info on how we can use the profiling tool with ignite-extensions modules?
