Nginx: Installation problems

Error: Package: moogsoft-ui-7.1.0-123.x86_64 (moogsoft-aiops) Requires: nginx >= 1.14.0

If you encounter the following error when attempting to install Moogsoft AIOps:

Requires: nginx >= 1.14.0
---> Package moogsoft-ui.x86_64 0:7.1.0-123 will be an update
--> Processing Dependency: nginx >= 1.14.0 for package: moogsoft-ui-7.1.0-123.x86_64
--> Finished Dependency Resolution
Error: Package: moogsoft-ui-7.1.0-123.x86_64 (moogsoft-aiops)
Requires: nginx >= 1.14.0

Try using --skip-broken to work around the problem, or try:

rpm -Va --nofiles --nodigest

Alternatively, you could manually install the Nginx repo with the following command and then re-attempt the Moogsoft AIOps installation.

rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-1.el7.ngx.noarch.rpm

Single-Host Installation for Non-Root 

If you cannot access the UI from your host machine, check your firewall and if you're listening on the right ports:

  1. To see if your firewall is enabled: 

    sestatus

    This returns the status disabled if the firewall is disabled.

  2.  To disable an active firewall:

    setenforce 0
  3.  To check whether a port is open:

    firewall-cmd --zone=public --query-port=8443/tcp
    firewall-cmd --zone=public --query-port=8080/tcp
  4. To open a port: 

    firewall-cmd --permanent --zone=public --add-port=8080/tcp
    firewall-cmd --permanent --zone=public --add-port=8443/tcp
    firewall-cmd --reload

Mobile Troubleshooting

Moogsoft AIOps includes a self-signed certificate by default. If you want to use Moogsoft AIOps for Mobile on an iPhone, you need to add a valid SSL certificate. This is because WebSockets do not work on iOS with self-signed certificates.

If a valid root CA certificate is not added, a 'Connection Error' appears at login and Moogsoft AIOps for Mobile does not work.

Nginx: SSL configuration

To apply a valid certificate to Nginx, go to the Nginx configuration directory and edit moog-ssl.conf :

cd common/config/nginx vi moog-ssl.conf
vi moog-ssl.conf

Change the default self-signed certificate and key locations to point to the valid root certificate and key:

#ssl_certificate /etc/nginx/ssl/certificate.pem;
#ssl_certificate_key /etc/nginx/ssl/certificate.key;

ssl_certificate /etc/certificates/GeoTrust_Universal_CA.crt;
ssl_certificate_key /etc/certificates/GeoTrust_Universal_CA.key;

Restart Nginx with this command:

systemctl restart nginx

Location of installation and log files

See Configure Logging.

Generic Moogsoft AIOps process not starting

No space left on the disk

  • Check the file system with the command df -m
  • Look for partitions that are full

<Service> not found
Error while loading shared libraries

  • Environmental variables may not be properly set up for your shell
  • Run the environment and check the location set for $MOOGSOFT_HOME

Moogfarmd not starting

Configuration parsing error

  • +|No config present|+ message in /var/log/moogsoft/moogfarmd.log
  • Points to a syntax error in $MOOGSOFT_HOME/config/moog_farmd.conf
  • Check the config file for punctuation mistakes

    Look for:
    • Missing commas
    • Unbalanced quotes
    • Missing {' or '} 
    Use # to comment out code instead of /* and */

  • Edit moog_farmd.conf and then restart the service

RabbitMQ

Also see Message System Deployment.

RabbitMQ: Not starting - "No such user"

  • No such user message in /var/log/rabbitmq/startup_err
  • Check /etc/passwd for user rabbitmq with the following command:
    grep rabbitmq /etc/passwd
  • If no user is found, add the following to /etc/passwd
    rabbitmq:x:491:488:RabbitMQ messaging server:/var/lib/rabbitmq:/bin/bash

RabbitMQ: Not starting - "Failed to create aux thread"

  • Failed to create aux thread message in /var/log/rabbitmq/startup_err
  • This is most likely a ulimit issue for the RabbitMQ user

  • Check ulimit settings for the RabbitMQ user by running the following command as root:

    su - rabbitmq
    bash-4.1$ ulimit -a
    core file size          (blocks, -c) 0
    data seg size           (kbytes, -d) unlimited
    scheduling priority             (-e) 0
    file size               (blocks, -f) unlimited
    pending signals                 (-i) 515675
    max locked memory       (kbytes, -l) 64
    max memory size         (kbytes, -m) unlimited
    open files                      (-n) 1024
    pipe size            (512 bytes, -p) 8
    POSIX message queues     (bytes, -q) 819200
    real-time priority              (-r) 0
    stack size              (kbytes, -s) 10240
    cpu time               (seconds, -t) unlimited
    max user processes              (-u) 1024
    virtual memory          (kbytes, -v) unlimited
    file locks                      (-x) unlimited
  • The above example shows ulimit settings that are likely too low for RabbitMQ

  • As per instructions here it may be appropriate to increase the ulimit settings for "open files" and "max user processes" to at least 4096 for development/QA environments and 65536 for production environments

RabbitMQ: Unable to create connection

  • "Unable to create connection" message appearing in a LAM, Moogfarmd, or Apache Tomcat logs
  • This indicates that the process unable to connect to the Message Bus zone in RabbitMQ
  • Check that the RabbitMQ server is running:

    service rabbitmq-server status
  • If the service is not running start it: 

    service rabbitmq-server start
  • If the service is running, check that the zone used in Moogsoft AIOps matches the vhost in RabbitMQ. List the zones (vhosts) added in RabbitMQ:

    rabbitmqctl list_vhosts
  • Check the MooMS section in /usr/share/moogsoft/config/system.conf for the zone used in Moogsoft AIOps.

  • If the zone is missing, add the zone (vhost) to RabbitMQ manually (see Message System Deployment).
  • Restart the affected process.

LAMs fail to start from command line

If LAMs run from the command line or as a service result in the following error:

[root@moogbox2 bin]# ./socket_lam 
./socket_lam: error while loading shared libraries: libjvm.so: cannot open shared object file: No such file or directory

it may be because /usr/java/jdk1.8.0_171/jre/lib/amd64/server has not been added to the LD_LIBRARY_PATH.

To run the LAMs via a command line, a change the  LD_LIBRARY_PATH  to be as follows (the default initd files contain this setting):

export LD_LIBRARY_PATH=$MOOGSOFT_HOME/lib:/usr/GNUstep/Local/Library/Libraries:/usr/GNUstep/System/Library/Libraries:$JAVA_HOME/jre/lib/amd64/server

Generic LAM not starting

Configuration parsing error

  • "Unable to parse configuration file" message in /var/log/moogsoft/<lamd_name>.log indicates a syntax error in the LAM configuration file.
  • Check the config file for syntax mistakes.

    Look for:
    • Missing commas
    • Unbalanced quotes

  • Compare the configuration file to a default configuration file for the same LAM. Use the following command to locate differences in the files:

    diff -y <current_lam>.conf <default_lam>.conf | less
  • Edit <current_lam>.conf to resolve any syntax errors and restart the LAM.

Connection refused error

  • "Failed to connect to [host:port]: Connection refused" error in /var/log/moogsoft/<lamd_name>.log means that the port specified in the LAM configuration file is already in use.
  • Use the following command to check that the LAM is not already started: 

    ps -ef | grep <lamd_name>
  • Check that another process is not already bound to the port.
  • If required, edit the port setting for the LAM in the configuration file and restart the LAM.

Unresolvable hostname error

  • "Host [hostname] unresolvable" error in /var/log/moogsoft/<lamd_name>.log means that the LAM is unable to resolve the host, or the hostname is incorrectly set.
  • In the LAM config file, check the address property and correct any errors.
  • Check that the /etc/hosts file contains an entry for the specified hostname.

Failed to open file error

  • "Failed to open file [<path to file>] error in /var/log/moogsoft/<lamd_name>.log means that the LAM is unable to locate a file specified in the LAM configuration file.
  • Locate the missing file in $MOOGSOFT_HOME/bots/lambots or $MOOGSOFT_HOME/contrib.
  • Update the LAM configuration file with the correct file path and restart the LAM.

Generic LAM not processing

Syntax error in Presend filter

  • In the LAM configuration file, locate the presend filter file name.
  • You can do this with a JavaScript editor. Check the code to locate any syntax errors. 
  • Or if you have installed Node.js you can run the following command to locate the incorrect line in the code:

    node $MOOGSOFT_HOME/bots/lambots/<path_to_filter_file>.js
  • Edit $MOOGSOFT_HOME/bots/lambots/<path_to_filter_file>.js to resolve the error and restart the LAM.

Empty columns in alert lists

  • Empty columns in alert lists may indicate incorrect field mapping assignments.
  • Check field mappings at the bottom of the LAM configuration file.
  • Edit the configuration file to properly map the field to the column name and then restart the LAM.

Socket LAM not processing

Processing mode set incorrectly

  • The LAM may be set to Server mode rather than Client mode in the configuration file. For a description of mode types see Socket LAM
  • Set the mode correctly in the configuration file and restart the LAM.

JSON feed not processing

  • The JSON string is incorrectly formatted. For example, event data contains nested JSON.
  • Run the LAM in debug mode and look for nested JSON.
  • Either modify the event data or edit the presend filter to match values in the nested JSON.

Logfile LAM not starting

No input file

  • "Could not stat file [-1] error: [Bad file descriptor]" error in /var/log/moogsoft/<lamd_name>.log shows that the Logfile LAM cannot locate the log file to read.
  • In the LAM configuration file check the target setting and confirm the file path to the target log file.

REST LAM not starting

Missing SSL path

  • +|No file path specified|+ message in /var/log/moogsoft/<lamd_name>.log
  • "No file path specified" error in /var/log/moogsoft/<lamd_name>.log indicates a missing SSL path in the LAM configuration file.
  • Check the value of the use_ssl property has been set correctly.
  • If using SSL, check the following properties are correctly set:
    path_to_ssl_files
    ssl_key_filename
    ssl_cert_filename

Nginx fails on startup if IPv6 not configured

Comment out the following references in two configuration files:

  1. Go to /etc/nginx/conf.d 
  2. Edit out IPv6 references with a hash #:

    Configuration FileSection
    moog-default.conf listen       80 default_server;
     #listen      [::]:80 default_server;
    moog-ssl.conf listen       443 ssl default_server;
    #listen      [::]:443 ssl;

User Interface (UI) issues

Unavailable UI Login Page

  • Check that port 443 is not being blocked by the firewall on the server.
  • Check that the Nginx service is running with command:

    service nginx status
  • Check that Nginx is listening on port 443. Example expected output:

    netstat -anp|grep 443
    tcp        0      0 0.0.0.0:443                 0.0.0.0:*                   LISTEN      42356/nginx         
    tcp        0      0 :::443                      :::*                        LISTEN      42356/nginx 

Login fails with "You could not be logged in. Please try again."

Apache-tomcat service not running

  • Check the apache-tomcat service is running:

    service apache-tomcat status

Communication problem between the UI and MySQL database

  • Check the MySQL service is running:

    service mysqld status
  • If MySQL is running on a different server, check that it is accessible from the Moogsoft AIOps web server and the required permissions have been applied.

Authentication problem between the UI and MySQL database

  • Check that the user exists in the MySQL moogdb.users table.
  • Check that the username and password used for authentication are correct.

Search/Elasticsearch

See Configure Search and Indexing for more information.

ElasticSearch not running or generating errors (such as MySQL connection problems)

  • Check that the Elasticsearch service is running:

    service elasticsearch status
  • Any errors are written to /var/log/elasticsearch/elasticsearch.log

Tomcat cannot connect to Elasticsearch

  • Check /usr/share/apache-tomcat/logs/catalina.out for any errors when attempting a search from the UI.

Cron job errors

  • Check that cron job that runs the moog_indexer (created by the moog_init_search.sh script to re-index against the Moogsoft AIOps database on a once-a-minute basis) exists and is not generating any warnings or errors.
  • List the configured cron jobs:

    crontab -l
  • Errors are written to /var/log/cron

  • Depending on the intervals at which Elasticsearch re-indexes against the Moogsoft AIOps database, it is possible that new alerts, Situations, threads or comments have not yet been indexed, and so will not be searchable.

  • To change the interval manually:

    crontab -ed

Elasticsearch fails to start with /tmp directory permission problems 

Elasticsearch fails to start with "java.lang. UnsatisfiedLinkError: /tmp/jna--<blah>" error. For example:

This is most likely due to the noexec directive in the /tmp mount. The solution is to remove the noexec directive, if it is practical to do so:

sudo mount /tmp -o remount,exec

Or set the following in /etc/sysconfig/elasticsearch:

ES_JAVA_OPTS="-Djna.tmpdir=/var/lib/elasticsearch/tmp"


Restart the Elasticsearch service after either of the above changes.

  • HTTP 409 -> Application Status Code 4000-4999

  • HTTP 500, 503 -> Application Status Code 1000-1999

Application Status Code [1000-1999]

Optional additional information

A debug message typically containing the exception message:

{ "debugMessage" : "java.net.ConnectException: Connection refused" }


Application Status Code [2000-2999] or [4000-4999]

Mandatory additional information

List of the bad parameter(s) and the error information:

{ 
	"name" 		: "parameterName",
	"value" 	: <badValue>,
	"errorCode"	: <errorCode>
}
