New Container View in infrastructure monitoring

 

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 and Elasticsearch API Security Features

The Sematext API for log ingestion and search has always been compatible with the Elasticsearch API and provides additional level of security, namely:

  • HTTPS encryption on all Sematext data receivers to help ensure the authenticity, integrity, and privacy of data in transit.
  • The API uses App’s token as index name and generates multiple read-only or write-only tokens in the App Settings. Log shipper requires the write-only token only and does not need to know the read-capable token, needed only if you want to query logs via the API.

Log searches via the API now require not only the App token, but also the API key as an additional security measure, yet no changes to any of your log shipping techniques are needed. This change affects access only via read APIs and not write APIs. Get your API key here and you can regenerate it 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 which allows third-party tools using client libraries with Basic Authentication for Elasticsearch to do the same. 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'

Better Servers View

Better Servers View

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.


Automatic Metrics Correlation

Automatic Metrics Correlation

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.


Added Logtrail to Kibana

Added Logtrail to Kibana

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.
