It seems like the issue might be related to either the Splunk Universal Forwarder configuration or log file permissions. First, ensure that your inputs.conf and outputs.conf files are correctly set up, with the right log paths and destination indexer details. Check the internal logs, such as splunkd.log, by navigating to /opt/splunkforwarder/var/log/splunk/ instead of /var/log. If no logs are present, verify that the Universal Forwarder has the right permissions to access the log files and is running properly. You can enable debug logging in the log.cfg file for more detailed output and restart the forwarder to apply any changes.

1.easy to expand 2.mesh network in which multiple redundant links exist between multiple nodes
A network topology is a description of the way computers are connected to each other and to other devices on a network. It can refer to the physical connections (the way the wires interconnect or the routing of wireless signals) or it can refer to the logical connections (the way computers can see each other or not see each other even though they have a physical connection. The topology can refer to a home network with a handful of computers and printers or it can extend to vast sections of the Internet. Some examples of topologies are ring, bus, tree, mesh and each describes the way the links are made. Network topology is a huge topic and the subject of more books than can be counted. A link is below that offers some simple examples of topolgy and might be a springboard for more study.
An old topology called Token Ring
Matrices are mainly used in network analysis to solve problems based on mesh and nodal analysis. Their applications are also used in network topology to solve problems based on tie set, cut set and incidence matrix.
Different types of Networking topologies are 1] Bus topolgy 2] Ring topology 3] Mesh topology 4] Hibrid topology
