ClickHouse key metrics in Sematext Cloud How to use it
You asked, we listened. The new Sematext Monitoring Agent includes many features that will make your infrastructure and application monitoring a whole lot easier.
The recently opened-sourced Sematext Monitoring Agent is fully pluggable, making it possible for you to collect metrics from a number of additional sources. The new agent supports the latest Java versions and has updates for many integrations such as Apache Kafka, introduces support for ClickHouse monitoring, etc. In addition, we changed how the agent talks to Sematext. Instead of using a custom protocol, we’ve adopted the popular Influx Line Protocol for sending metrics and all their metadata via HTTPS. The old proprietary format will continue to work for a while to ensure backward compatibility with older agent versions.
You can find all details about the release in Open-sourcing Sematext Monitoring Agent.
The agent update is super simple: just use your package manager to update the spm-client package.
- New colors to improve accessibility
- Vega interactive visualizations
- Ability to apply Vega filters to dashboard context
- Visualization of other and missing terms buckets
- Lab visualizations
- Improved workflow for inspecting data
- Dashboard input controls
- And more!
The new Containers view provides you with enhanced visibility into all your containers and their hosts, drawing your attention to the ones that need it the most.
The main view is very much like “top for containers” – applied across all of your containers and their hosts. You can sort containers by memory or CPU usage to find the hottest containers, or simply display the top N containers. The detail view of each container displays container metrics in real-time.
In containers table, the user can see basic information and metrics about each server and by clicking on table row user can expand it to get more details about the container. Thus, for each container user can view metrics, review information about containers grouped by tags like host, image name, pod name …
By using the heatmap, user can get an overview of a large number of containers at once and see if selected metric has a high value on any of the monitored containers or host.
Sematext Logs Elasticsearch API Extra Security | July 2018
The Sematext API for log ingestion log search has always been compatible with the Elasticsearch API. On top of that, the Sematext API has always had additional security in place, for example:
- HTTPS encryption on all Sematext data receivers
- The API used the App tokens as index name, with the ability to generate multiple read-only or write-only tokens in the App settings. For example, somebody who needs to set up a log shipper really requires only the write-only token and doesn’t need to know the read-capable token, which is needed only if you want to query logs via the API.
To further secure access to our customers’ data we now require not just the App token, but also the API key for log searches via API. Importantly, note that you do not have to change any of your log shipping.
This change affects only access via read APIs, not write APIs. You can get your API key from https://apps.sematext.com/ui/account/api and, as you can see there, it can be regenerated at any time should it ever get compromised.
The following example shows a search request with curl using the new authentication header:
curl 'https://logsene-search.sematext.com:443/<APP TOKEN HERE>/_search?size=0&pretty' -H 'Authorization: apiKey <API KEY HERE>'
The API also supports HTTP Basic Authentication. Therefore third-party tools using Elasticsearch client libraries that use Basic Authentication with Elasticsearch can authenticate as well. The username is then the “apiKey” literal, and the password is the actual API key. Here is another example using curl with basic authentication:
curl -v -u apiKey:<API KEY HERE> 'https://logsene-search.sematext.com/<APP TOKEN HERE>/_search?size=0&pretty'
Servers view is giving overview over host servers used by your apps. User can use GroupBy and FilterBy filters to decide which servers or group of servers he wants to monitor. There two main components for monitoring: table-view and heat-map.
In servers table user can see basic informations and metrics about each server and by clicking on table row user can expands it to get more details about server. Thus, for each server user can view metrics, review informations about docker containers on that host and review metrics and informations for apps on that host.
By using heat-map user can get overview over large number of servers at once and see if selected metric has high value on any of monitored servers.
If you work with monitoring or monitoring tools much, you’ve probably seen the phrase “correlating” here and there. Correlation is what can help you find metrics with similar pattern and see dependencies between metrics even if you don’t suspect they are in dependency relation. When troubleshooting, automatic metrics correlation is the easiest way to find root cause.
Automatic metrics correlation in Sematext Cloud work pretty straight forward: you select a metrics of interested, select time range and Correlation mechanism will find all metrics which have similar behaviour in the same time range. Similar spikes, similar trends, similar waves.
Dealing with log files or extracting data from various data sources is a daily task in the IT administration. Adding logtrail to Kibana gives users the “terminal experience”, that experience of tailing and filtering log files like in the good old terminal that tons of people are used to and that many of us still love – typically black background, new logs appearing at the bottom of the screen instead of the top screen, simply way to filter logs and “jump” to various parts of the log stream.
To summarise this plugin enables you and your team to view, analyze and search log events from a centralised clean & developer friendly interface.
