The joint enterprise performance products will be pre-integrated, reducing users' workload.
Performance management software supplier InfoVista, and Micromuse, which produces system uptime assurance software, said the joint tools fill gaps in both companies' products.
Micromuse will sell InfoVista's performance management products as the Netcool/Vista product family. InfoVista will sell Micromuse's agent software for managing systems and applications.
The Netcool/Vista product family now includes performance management and reporting for systems and applications, IP telephony, IP VPNs and core networks. Other features include real-time fault monitoring and analytics, historical trending, business impact analysis and executive dashboard views.
Micromuse's chief technology officer Craig Farrell said the software's analytics could help predict when high user activity will cause a network slowdown.
"InfoVista's real-time analytics capability sets it apart from competitors as a superior solution for predictive performance management," he said.
Micromuse and InfoVista will compete with IBM Tivoli, BMC, Hewlett-Packard, Computer Associates and Mercury Interactive.
Bill Clough, research director at analyst firm IDC, said the systems and network management software market in Europe is now worth £1.81bn, driven by firms adopting utility computing and attempts to get more from heterogeneous infrastructures.
"The major suppliers are pushing the envelope on performance monitoring, measuring and reaction systems," he said.
