Troubleshoot performance issues using Real-time Protection Statistics Multiple security products may conflict and impact the host performance. In particular, applications or system processes that access many resources such as CPU, Disk, and Memory over a short timespan can lead to performance issues in Defender for Endpoint on Linux.īefore starting, please make sure that other security products are not currently running on the device. Sometimes applications are sensitive to disk I/O resources and may need more CPU capacity, and sometimes some configurations are not sustainable, and may trigger too many new processes, and open too many file descriptors.ĭepending on the applications that you are running and your device characteristics, you may experience suboptimal performance when running Defender for Endpoint on Linux. Performance problems are mainly caused by bottlenecks in one or more hardware subsystems, depending on the profile of resource utilization on the system. This document provides instructions on how to narrow down performance issues related to Defender for Endpoint on Linux using the available diagnostic tools to be able to understand and mitigate the existing resource shortages and the processes that are making the system into such situations. The Safe_ports and SSL_ports is the squid.Want to experience Defender for Endpoint? Sign up for a free trial. Proxy-only no-query no-netdb-exchange default login= : I thought this line in nf was supposed to send the traffic to an upstream cache_peer parent gateway, but I could easily be misunderstanding what its supposed to do.
If I configure a browser to use the proxy server and browse to some websites, it can get to http sites, but not https sites. The traffic never reaches the McAfee gateway. However, once the traffic goes through the proxy, it tries to go directly to the vendor website and not go through the McAfee gateway, and therefore is getting blocked by the firewall. If it tries to take a path different than that upstream gateway to get out to the internet, it’ll get dropped.
The traffic needs to go through the squid proxy, through a firewall, and through an upstream McAfee gateway server. I need for a MS WSUS server and a Symantec Endpoint Protection Manager to get through a squid proxy to get out to Microsoft and Symantec respectively to get MS patches and Symantec DAT files. I’m having issues getting squid to send traffic through a specific upstream gateway.
