Getting Started

A: If other Solr/ES charts are showing the data, it is most likely that there were no requests sent to your Solr/ES in the time range you are looking at. Try sending some queries and see if request rate/latency charts will show them. If they don't, please send us an email to spm-support@sematext.com or contact us in chat.

I am not seeing any data in SPM charts, how do I check if network connectivity is OK?

A: SPM agents send the data to SPM backend (hosted on sematext.com machines) so it is important that machines where you install SPM agent can access the internet. Things to check to ensure network connectivity is ok:

1. Try connecting to spm-receiver.sematext.com with the following command:

Code Block
nc -zv -w 20 spm-receiver.sematext.com 443

The output should show something like: Connection to spm-receiver.sematext.com 443 port [tcp/https] succeeded!

In case you see some other result:

  • if your machine requires proxy to access the internet, you can define its settings in /opt/spm/properties/spm-sender.properties. After that restart SPM agent.
  • if firewall is used to protect your machine, it may be blocking outbound traffic from it. SPM agent sends the data over port 443, so please ensure with your network admins that port 443 is allowed for outbound traffic
  • check your DNS (see below)

2. Check if your DNS has correct entries for SPM receiver:

Code Block
getent hosts spm-receiver.sematext.com

The output of this command should look like (IP addresses and names may be somewhat different):

Code Block
50.16.206.179   SPM-Prod-Receiver-LB-402293491.us-east-1.elb.amazonaws.com spm-receiver.sematext.com
107.20.222.136  SPM-Prod-Receiver-LB-402293491.us-east-1.elb.amazonaws.com spm-receiver.sematext.com

If you see different output, you may want to check with your network admins if everything with your DNS is ok or may need adjustment to be able to reach spm-receiver.sematext.com.


I registered for SPM more than 5 minutes ago and I don't see ANY of my data / I am getting errors when starting SPM Monitor or when starting my service which uses javaagent version of SPM monitor, what should I check

...

A: Filters have 1 day granularity, which means that a server will be listed under Hosts filter until 24 hours since it last sent data have passed.  For example, if a server stopped sending data at 1 PM and if at 8 PM you are looking at the last 6 hours of data (for a period from 2 PM until 8 PM) you will not see data from this server on the graph, but you will still see this server listed under the Hosts filter until 1 PM on the following day.  After 1 PM on the following day this server should disappear from the Hosts filter.

I rebooted my server and now I don't see any data in my graphs. What should I check

...

I am using SPM for Solr and I don't see any data on Solr and JVM reports, what is the problem

A: You should probably enable JMX in your Solr. Add or uncomment the <jmx /> directive in solrconfig.xml and restart Solr.  See http://wiki.apache.org/solr/SolrJmx for more info.

I am using SPM for Solr and I don't see any data only in Solr Components or Errors reports, what should I do

A: Most likely you are using standalone variant of Solr monitor. In that case, SPM monitor can't collect metrics which are available only when running in-process. If so, switch to in-process (javaagent) version of SPM monitor.

Elasticsearch Monitoring

Why doesn't the number of documents I see in SPM match the number of documents in my Elasticsearch index
