When the BIG-IP system is licensed with BIG-IP APM, a separate set of processes is initiated in addition to the standard set of BIG-IP processes. The following table lists the core BIG-IP APM services, and indicates the impact to the BIG-IP APM system operation if the service is not running:

F5 BIG-IP APM daemons (11.x)
Daemon	Description	Impact if not running	Relevant log files
acctd	The RADIUS accounting daemon used by BIG-IP APM to send RADIUS accounting start and stop messages to external RADIUS servers.	RADIUS accounting messages are not sent to external RADIUS servers.	/var/log/apm
aced	The aced process provides RSA SecurID authentication functionality for BIG-IP APM’s access policy engine.	RSA SecurID authentication fails.	/var/log/apm
apd	The apd process runs a BIG-IP APM access policy for a user session.	No access policy enforcement.	/var/log/apm
apmd	The apmd process provides an MPI interface for BIG-IP APM access policy execution.	No access policy enforcement for MPI reliant processes such as rewrite and websso.	/var/log/apm
antserver	The antserver process allows Secure Web Gateway (SWG) to dynamically filter web content.	No dynamic web content filtering.	/var/log/apm
dnscached	The dnscached process provides DNS cache functionality to BIG-IP APM subsystems.	BIG-IP APM DNS performance is impaired.	/var/log/apm
eam	The eam process provides external access management for 3rd party identity integration such as Oracle Access Manager (OAM) SSO.	OAM SSO authentication fails.	/var/log/apm
eca	The eca process provides the client-side NTLM authentication mechanism.	BIG-IP APM is unable to authenticate using NTLM.	/var/log/apm
logd	The logd process provides database-backed local logging for the BIG-IP APM system.	BIG-IP APM local logging functionality is impaired.	/var/tmp/logd.out
nlad	The nlad process establishes communication channels to the Domain Controller (DC) for NTLM authentication.	No NTLM communication to back-end DC.	/var/log/apm
omapd	The omapd process provides the IF-MAP server implementation for SWG and AFM^™ user identification.	No user identification for SWG.	/var/log/omapd
rba	The rba process provides support for client-side Kerberos authentication.	No Kerberos authentication.	/var/log/apm
rewrite	The rewrite process rewrites links in web content for Portal Access.	Portal Access web links are not rewritten.	/var/log/rewrite
samlidpd	The samlidpd process interacts with the mcpd process to automate SAML IdP connector creation.	SAML IdP connector creation fails.	/var/log/saml_automation.log
urldb	The urldb process categorizes incoming URLs for SWG.	No SWG URL categorization.	/var/log/apm, /var/log/urldb-trace.log
urldbmgrd	The urldbmgrd process downloads and indexes the URL categorization database for use by the urldb process.	URL categorization for SWG is impaired.	/var/log/apm, /var/log/urldbmgr-trace.log
vdi	The vdi process handles communication for XML-based clients and backend systems, such as Citrix and VMware View.	Citrix integration and RDP access fails.	/var/log/apm
websso	The websso process provides Single Sign-On (SSO) functionality for the BIG-IP APM system.	SSO fails.	/var/log/apm

Starting and stopping BIG-IP APM processes

You can use the command line to manage BIG-IP APM processes. To stop, start, or restart any BIG-IP APM processes, use the following syntax with the bigstart command:
